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.
Oh, hush now, of course I care! I’m just agreeing with OP that there is probably a little too much of it or, more precisely, not enough “other” topics of conversation yet. It’ll come.
