One of the things I like about #mastodon is that one can follow hashtags. It might not be a foolproof method but it is a more transparent way than algorithm heuristics to see posts from people you don't follow. The user is still in control!
Mastodon is the best way to keep up with what's happening.
Follow anyone across the fediverse and see it all in chronological order. No algorithms, ads, or clickbait in sight.
