Bluesky is a lot easier to use vs fediverse stuff, discovering stuff is also easier in my experience vs mastodon.
the problem is its easier to use because there is virtually no federation. Ive yet to see a user thats not from the flagship bsky.social instance
Maybe you’re already aware, but bluesky doesn’t operate with instances like in ActivityPub land.
I’ve seen many people I believe are using their own PDS, but yes, discoverability is likely better because a relay is meant to aggregate and share all data it can (look up “bluesky firehose”).
P.S. Mastodon’s devs are part of a new initiative to improve this area of the Fediverse. Because it’s so recent, we’ll have to wait to see how it goes.
