The entire point is that your pds can interact with multiple “instances” of bluesky or whatever other apps people build on the protocol.

For example there is a reddit/hn clone that people can post on (keeping their same identity) when the official bluesky service goes down. The reddit clone is fully independent from the twitter clone, but they use the same protocol and (unlike AP) the same hosting and authentication infrastructure.

Whereas on Lemmy and mastodon, my accounts are totally separate. And unlike AP, your data lives on your own pds and is never hostage to the owner of the instance that actually runs the load bearing interactivity. If they become compromised or shut down you can switch to another. No cooperation from the old owner required (unlike activitypub).

Bluesky is not making a reddit alternative, a third party developer is using their hosting/auth infrastructure.

I asked the devs about this and they said that bluesky is designed to be a) modular b) trustless as much as possible. federation is supposed to happen on the trustless hosting and relay layers - you can ask your posts to be crawled by any indexer/appview.

But once you get to the indexing/querying layer, there are no more merkle proofs to keep everyone honest, so there is no point in federating because any indexer can modify/censor the content they send to another indexer instance. So you could still build an api to interact laterally between servers, but it wouldn’t be atproto anymore.

Bluesky (well, atproto, bluesky is the twitter clone running on atproto as a demo app) doesn’t actually have instances in the mastodon sense, it’s a more modular design for better scaling (because it was designed from the start to replace twitter)

Here’s a good article with illustrations https://atproto.com/articles/atproto-for-distsys-engineers

That the universal ports are worse for some purposes than the old specialized ones. I feel this especially for magsafe and analog audio

no, no, he has a point

That post refers to hosting an appview that does all the same things as the official bsky (the service) one, which involves a ton of storage and bandwidth and processing (for everyone’s recommendations, notifications, and all the other moving parts), and is closed source to boot.

Frontpage.fyi is a lot cheaper simply because its used by like 50 people tops.

Because we live in a capitalist hellscape and the companies that implemented these tricks were the fastest growing segment of our economy for like 15 years (esp after the 2008 crash) so the government turned a blind eye. Now they control the world and are able to literally buy politicians

There are already smaller appviews that use the existing hosting/authentication infra, but bypassing the bsky appview aggregation. Nothing with any real scale but for example there is a barebones reddit/hackernews equivalent https://frontpage.fyi/

Things like using surveillance to figure out when your payday is and raising prices (just for you, and just on that day) because you psychologically are more willing to spend in that moment

Unfortunately a lot of our peers are also tech illiterate :(
