It's a different approach with different ideas. It uses open protocols, focuses on data and account portability, and incorporates peer-to-peer concepts in its architecture. The vision behind Bluesky is to build a global square with these concepts.
I definitely wish they would've extended ActivityPub and collaborated on the wider network, but I kind of understand wanting to start from scratch and not get involved with the cultural debt Mastodon brought to the network.
Come now Sean, you know that everything open about BlueSky is smoke and mirrors, considering that everything stops and starts with the indexer.
I can't tell whether this is serious or sarcastic 😅
As far as the "global square" part of the equation is concerned: yeah, you're right! A firehose of public statuses requires indexing to work, as a basic foundational premise.
However, there's nothing preventing someone from standing up a PDS, opting out of the firehose / big graph service, and instead leaning on federation between individual PDSes. I'm not saying it would necessarily be a common use-case, but it's definitely not impossible.
Isn't that the same issue with ActivityPub and the instances that host accounts and messages?
No. With ActivityPub, it's totally decentralized. There's no central authority whatsoever. What there is however, is an instance that's bigger than the rest. So if we talk about Lemmy. I can access it and post and my ISP can block Lemmy World and I'd never know.
With BlueSky, it pretends to be similar, but the reality is that everything needs to go through their central server in order to be displayed on a timeline. BlueSky is designed in such a way so that everyone does the heavy lifting, but to be seen, you need to have approval from their central server, where they can modify, insert adverts, do whatever. It's a centralised service that cosplays as decentralised. I don't understand why people keep pushing it when it's literally the same shit we all escaped from but with a new paint job.
They have been saying that this is an implementation detail that will change when they open up that part of their implementation. Which is nice, but until that happens I'm only lukewarm in my optimism for Bluesky and the AT protocol.
On the other hand, every federated network has converged on a central host for the vast majority of accounts and data. That host has outsized influence over the standard used on the network and unencrypted acess to the majority of data. So I'm not sure what really matters to what extent.
I'll tell you why I signed up. Because I'm a non-techie, and didn't KNOW any of that.
I don't see any need for BlueSky at all when there already is a great network in the form of Mastodon. I mean all (most) of the ideas you mentioned apply one-to-one to Mastodon as well. To me they have very similar ideas.
Unlike ActivityPub, account migration with the AT protocol should allow to move content.
Mastodon's moderation model is very different than BlueSky. BlueSky's seems to be much better for targeted individuals and groups. But things aren't entirely hashed out on either protocol or their implementations. We'll see how it goes.
