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.
That would probably be why you’re having difficulties finding anarchists on Mastodon. “If you want your boomerang to come back well first you’ve got to throw it.”
