@katzenmann@c3d2.social Hey! Been checking out #activitypub today, but I come from #atproto land. Relays have gotten pretty cheap to run now, thankfully. They used to keep a mirror of the whole network, but now only keep a couple of days. Can squeeze by with less than $40 on them nowadays, or even cheaper. https://whtwnd.com/bnewbold.net/3lo7a2a4qxg2l. We also have a bunch of community ran ones, a few listed at this beautiful URL lol https://compare.hose.cam. Relay's also don't directly do feed aggregation, but they do feed the feed with the posts. But that can also be swapped out between relay's or even something called JetStream, which is a diet relay. Feeds listen to this firehose and filter out posts on how it wants, like which content it wants to show. For instance, here's a feed URL for posts about cornbread lol https://api.graze.social/xrpc/app.bsky.feed.getFeedSkeleton?feed=at://did:plc:rnpkyqnmsw4ipey6eotbdnnf/app.bsky.feed.generator/Cornbread The feed just returns the at-uri's which can be used to hydrate the feed from getting posts from an AppView or connecting directly to the user's PDSs
