I never figured out how to use Mastodon and the likes. Can somebody explain? I mean, I would know how to use it if my goal was self-indulgent shitposting or very questionable marketing strategy, but these services are always mentioned as an alternative to Twitter, and Twitter is primarily a news-feed (which probably works because some other famous people are engaged in shitposting and marketing strategies, but this is none of my concern — for me it's just a news-feed).
