When I tried Mastodon, I found I couldn’t get the content I’m interested in there. I’m not really interested in following specific people; instead I want to see posts that fit my interests, regardless of who made them. Hence (apparently very unpopular on the Fediverse), I actually want an algorithm that can create a personalized content feed for me. Is there a platform that has that?
As others have mentioned, between Mastodon’s hashtag following and now Threadiverse communities, that’s all I need to feel plugged into various topics I care about. I’m not sure what more a feed algorithm could do for me.
