One cool feature that Twitter briefly had, way back when, was the ability to see the feed of another user. Like, construct a feed of all the accounts this person is following, since it's all public information anyway.

It was a great way to find new people to follow. I'm sure that's easily doable with a custom Mastodon/ActivityPub client, dunno about Bluesky.

This would be great if Bluesky still wasn't invite only.

I got invited a while ago but unfortunately I’m invites broke or would’ve invited you. That being said, haven’t yet used it.
