Haven't we learned by now that approximately no one cares? Centralised services are vastly more popular than federated ones, the main reason being that they reduce the paradox / paralysis of choice when you're signing up for them. (Solve that problem properly and you may be on to something.)
I thought I had it (mostly) solved with fediverser: users would go to one place, sign up with OAuth to the service they wanted to leave (Reddit, Twitter...) and the system would behind the scenes create an account on any of the participating instances. In doing so, it could leverage the user existing information (subreddits subscribed, users followed on Twitter) and find the corresponding subreddits/users that are already registered.
Turns out the biggest challenge was not in getting users, but in convincing admins to join the network. Instances with open registrations are already dealing with spammer accounts, and none of them was excited about the idea of this extra vector for having unvetted users on their services.
This doesn't mean that centralized services are safe, though. I am reasonably convinced that we can have "social media" that is less focused on "platforms" and more like what we (used to) have with web: companies and institutions owning their presence by running ActivityPub "servers" on their own domain, and a hotch-potch of community/commercial servers to serve the users who want "basic access".
But to get there, we need to stop thinking that the way to get rid of Facebook/Twitter/Reddit/Instagram/YouTube is by taking their templates and tacking "but federated!", and we need to really come up with a killer app on ActivityPub (or Solid, or Linked Data, or ActivityPods) to disrupt the whole thing entirely.
I'm pretty sure the ATproto answer to that is "don't bother users with that decision", i.e. just point new users to somewhere (be it bsky.social or some other PDS provider) and call it a day. This "works" from a decentralized/federated point of view because ATproto supports migrating accounts/identities between PDSes even if the old PDS is offline or adversarial, and because account/identity hosting (i.e. the PDS) is decoupled from the app itself (i.e. the appview) - so even if you signed up as @foo.example.app instead of @foo.bsky.social, you can still log into Bluesky as @foo.example.app (and likewise, @bar.bsky.social can still log into Example App), and if Example App (or Bluesky, for that matter) ever kicks the bucket you can migrate your account (and its followers, and very likely its public content, and possibly its private content if that was backed up somewhere) to someplace else.
Definitely agree that centralized services have a lot of advantages. Bluesky deserves some criticism for trying to have their cake and eat it too, though. They told a good story about being decentralized, and lots of people repeated it while ignoring technical experts pointing out it's not true. Even on HN, the claim that they're decentralized was repeated a lot.
Exactly. There's a lot of dogmatic hype with atproto, which is kinda giving me early crypto/NFT vibes. Any discussions or criticisms are quickly snuffed out or labeled as toxic or uninformed, or devolve into whataboutism.
A lot of the content on bluesky, but especially in its early days, is about how the protocol is great, its potential and what bright future it will lead us into. Their main investors are a crypto bro company. Their CEO has built her career around crypto. It's the same rhetoric.
Now it's about decentralized "verification". They still haven't defined what they're verifying except a vague term "the person posting is who they say they are", but it's not actual identity verification.
The endgame is probably monetizing the protocol by connecting it to some form of identity for crypto-bs or paywalling engagement via the verification.
Email has solved federation / decentralisation long before WWW.
Nobody is confused when you hand them a user@gmail.com, user@hotmail.com, etc; I use my own user@whatever.com and sometimes get a blank stare, until people realise you can go to www.gmail.com to check your own inbox, and you can totally just type www.whatever.com into your browser.
Links like reddit.com/u/user, youtube.com/@user, already exist and are de facto a standard of some kind. If we stop trying to make @user@whatever.com a thing, the only obstacle is in convincing people that whatever.com/user is just another link you can click, and this is totally how they can reach you - send you a message.
Federation between servers is an entirely different topic, but for the purpose of this discussion we can assume it's just an implementation detail - just like SMTP is for GMail users.
I'm probably making this sound more trivial than it actually is, but IMO all you have to do is build up on existing paradigms and collective understanding.
The main reason is that they have marketing of a corporate entity behind them and someone to sign a contract with.
I've seen many times - company switching from free, open-source, distributed solution to a worse, closed-source, coporate-backed solution just so they have someone to sign a contract with.
First time it was moving from self-hosted Jabber to MSN Messanger (is sucked, worked less reliably than self-hosted jabber, didn't worked on Linux, and was probably way more expansive in the long run). Then it was moving from self-hosted wikis to some B2B solution. Then it was self-hosted git to corporate github or sth similar.
I understand the theory behind outsourcing these things, especially if you're just starting. But if you already have the OS solution deployed and working - why switch?
The first startup I worked for had 1 IT guy among 12 people, and everything was in-house, including servers. The second grew to 50 people and did not ever employ an IT guy for internal work - most stuff was run on SaaS and the total cost was less than an IT guy salary. Any admin was done by taking engineering time, and no-one wanted to divert that away from product to do in-house stuff. Because when you're taking time away from product, it's not just the salary but the opportunity cost, because any investment in product is supposed to return a multiple.
And you know what would be even cheaper (in the medium/long term) than the IT in-house or outsourcing to commercial SaaS? If the company took 10-20% of their budget to sponsor the development of FOSS alternatives.
The issue is that relays tend to require a lot more resources to operate than appviews and PDSes (though not necessarily as much as that blog post suggests; I recall posts of people running their own relays on RPi4s with NVMe drives), so it's common for alternative appviews to rely on Bluesky's relay instead of taking on the expense of spinning up a new one.
In any case, as that toot notes, the Bluesky outage was on a PDS level rather than a relay level. And thankfully it's much less expensive to run your own PDS; apparently those who do so weren't impacted.
Genuine question: if it's so easy and cheap to host a relay, why then "Free Our Feeds" initiative [0] looking to raise $4,000,000 [1] to establish a second relay [2]? Most of that money must be earmarked for administrative and human expenses then, right?
That wasn't asserted anywhere. Quite the opposite: as I explained above, the expense is why few people have done it (and even fewer have done it in production). It's the PDSes which are (relatively) cheap and easy to self-host.
> why then "Free Our Feeds" initiative [0] looking to raise $4,000,000 [1] to establish a second relay [2]?
Per the section you cite, they're doing a lot more with that money than running a second relay: they're spinning up an entirely separate organization independent of Bluesky to develop ATproto and applications using it. That includes, but is nowhere implied or explied to be limited to, the "second relay" they mention.
In any case, even the self-hosted relay described in that above-linked blog post (let alone some RPi under someone's bed) is in all likelihood a long ways off from one that's even remotely production-ready. There's no mention of redundancy, no mention of future-proofing, etc. It's reasonable to assume that the "second relay" would be multiple such relays, likely on machines with even beefier specs - in other words, at least as capable as the existing Bluesky-managed relay. I'd also be unsurprised if it expanded to a "third relay" and "fourth relay" and so on.
Further, there's more to running a relay than just the hardware; you need someone to maintain it. $4 million pays for 40 employee-years (assuming every employee is full-time with an annual salary of $100k). That could be one sysadmin for 40 years, or an 8 person team for 5 years, or a 40 person team for 1 year, or what have you. Free our feeds claims they'll need $30 million over 3 years, i.e. $10 million per year; if half that goes to salaries, we end up with a napkin-math-guesstimated team size of 50 - which is about the size I'd expect for an organization that wants to independently maintain a bunch of technical infrastructure, develop applications, prod whomever needs prodded to get ATproto formally standardized, etc.

> I recall posts of people running their own relays on RPi4s with NVMe drives
I would absolutely consider software I can host at home, on a RPi, cheap and easy to self-host. That's the assertion that's being called out here. Bluesky's relays do not scale down easily, and are difficult and expensive to host
> I would absolutely consider software I can host at home, on a RPi, cheap and easy to self-host.
That's expensive and difficult compared to running a PDS or appview (either of which can run with a tiny fraction of even an RPi's resources), which is exactly what I said. And to reiterate: an RPi4 with an NVMe SSD is very far off from something that's production-ready and suitable for public use. You can run your own relay, but it's probably not going to handle 30+ million users like Bluesky's relay does, or like Free Our Feeds' "second relay" presumably seeks to do.
Scale, its always question of scale. Whatever youncan easily and cheaply host yourself will likely be only good enough for you and your friends or family. Anything more will require more hardware and dedicated people for maintaining that hardware and software.
the relay at this point is non-archival and can be spun up trivially. with a small sliding history window for subscriber catchup u can use like 32gb of scratch disk space and keep a few hours, the relay is literally just a subscribeRepos forwarder from PDSes.
the AppView is vastly more expensive to run since you need to handle the write volume of all bsky activity. if you build a non-bsky app on atproto this is a non-issue
the issue here really is that nobody writes about the state of things in long form outside the network so it's not really known how fast things move and change by those not engaged with the platform
The genie is already out of the bottle for thirty years, and it's called the open web. Luckily I don't need half the world's population to agree upon and use something that already exists out there.
Keep posting on your website and keep linking. It's called the 'web' for a reason.
You know why it's called the web? Because all the websites and webpages linking to each other form the shape of a web. I don't know what shape the internet is going to be, but the web is shaped like a web. Also tomorrow.
I love the web, but it is also clear that much of the internet is now a hub and spoke model. Client/server, in other words. The difficulty was always matching clients with different servers, and the centralised services never had to solve it.
i don’t actively contribute to Bluesky nor Fedi (i do consume content from both), but it’s pretty frustrating to see BlueSky being argued into a centralized service for the recent downtime.
- The downtime was not relay level, but it was a PDS level. So the point is moot already.
- Because it was decentralized at the PDS level, the outage did not affect anyone with personal PDSes, which contains the data that you care about.
- Even if it was the relay level, relays aren’t centralized, anyone can spin up another relay (because everything on the relay is derived from PDS data). It’s just that it’s going to be pretty expensive and consume much resources. Which is a fair point, and might be argued that the network currently has a single big point of failure, but that doesn’t mean it’s centralized.
And then people now start arguing that the fact that BlueSky-hosted PDSes went down at the same time is now another proof that BlueSky is centralized?
That’s like arguing that Gmail can go down and all @gmail.com mail addresses won’t work, so email is centralized. Or AWS can have an outage and all AWS-powered websites will break down, so the web is centralized.
One can say that there’s a single big point of failure (which the BlueSky LLC is, just like AWS, Gmail, or the mastodon.social instance in the case of Fedi), but that doesn’t make the whole service centralized.
Yeah lots of the commenting online seems in somewhat bad faith about this.
I’ve listened to interviews with the Bluesky CEO and the Mastodon founder (CEO?), and it was quite eye opening. They have very different views on their roles. The Bluesky CEO is thinking at the level of community building, incentives, longevity, and decentralisation at a fundamental level, whereas the Mastodon founder seems primarily motivated by building an open source project and supporting contributions from the community.
Neither approach is wrong, but they’re different and are clearly achieving different things.
Mastodon might be easier to self host on the surface, being just another Rails site, but the result isn’t a “world without caesars”, it’s a world with a lot more caesars, where anyone can be one. Migrating instances is roughly impossible if you have any presences you want to preserve, and ActivityPub compliance is essentially defined by Mastodon’s current behaviour.
Bluesky on the other hand seems to so far be far more successful at the community building and laying out the protocol foundations, at the cost of being harder to self host. But honestly, having self hosted Mastodon and switched (and forced to start again in the process), so what? Hosting a PDS is trivial and that’s the bit that really matters anyway.
Mastodon should be recognised for how much it shifted the conversation around social networking, especially in the first year after Twitter’s acquisition, but it seems clear that Bluesky has some fundamental advancements that Mastodon fans seem unable to recognise simply because it looks so different.
Decentralization doesn't really help, it only creates more bubbles.
Reddit is extremely centralized, and you can find hundreds of subreddits that do cover Israel's ethnic cleansing. However, most popular subreddits are heavily censored, while the smaller communities become an echo chamber, and often get radicalized.
Decentralized bubbles are still bubbles—even worse, since the barrier to entry is higher.
LinkedIn's approach has been to segregate pro-Palestinian content to a bubble where it's not shown to people outside it. Now, that is believed to be because they are deliberately trying to limit pro-Palestinian liberation content due to the extremely pro-apartheid and pro-occupation beliefs of their CPO Tomer Cohen, but it's none the less pretty effective.
or activitypub ! Part of w3c, tons of servers and clients, even Meta runs an instance
I don't think it's as easy to run nostr relays as activitypub instances but maybe I am wrong. ActivityPub seems way more active than nostr also. Most of what I see on nostr is either cryptocurrency discussion or the kinds of alt-lite content you would find on Gab or Minds
Nostr relays are in essence extremely dumb websocket servers. The most popular relay software is nostr-rs-relay a single binary written in rust that automatically spins up an SQLite database.
Bitcoin discussion yes, but mostly because bitcoiners are avid self hosters. Cryptocurrency not much. The “crypto” people created their own thing if I’m not mistaken.
Nostr was spun out as a truly censorship resistant protocol so it’s a given people who distrusts both centralized services and island style moderation are there don’t you think?
dergigi once described Nostr with an analogy to a gay bar. The place is nice, the furniture is fancy, the drinks pleasant and the people who frequent it are mostly nice but if you are not gay you won’t stick for so long.
Nothing keeps you from creating a moderated relay or curate your feeds though.
One of the coolest things about Nostr IMO is how extendable the protocol is and how easy you can develop crazy stuff for it.
Ah and for some reason there are some Japanese users.
Nostr is super flexible too since its a protocol. I see reddit-style and hacker news style sites, documentation sites, blog sites...and yes twitter/x style sites as well.
Hell there's even a streaming platform on nostr too. The common criticism is that its all bitcoiners, that's mainly because it uses Lightning Network for zaps and that's how people get paid in nostr. So naturally its a lot of bitcoiners in the nostr communities.
