I feel like 75% of Mastodon are people talking about Linux. If you don’t care about Linux you feel alienated. I enjoy Mastodon and Lemmy, but the lack of more diverse subjects gets to me if I browse for too long.
Update: I took your advice and purchased a laptop for Linux, and now I care about it! Problem solved.
I don’t like only browsing subscribed communities because otherwise I never see anything outside of a bubble. Also subscribing to big communities means I miss anything important in the small ones.
One of the biggest failings of the fediverse in my opinion is the complete lack of any kind of decent algorithm. People rallied so hard against them that we now have the opposite problem, discoverability is next to 0 on this platform. I love an algorithm that actually works and recommends what I want to see.
Now I get that it’s unpopular with the current user base, but I’m going to guess it’ll be a problem sooner or later when new users decide to go elsewhere because of algorithms.
