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 think it’s in mastodon and not lemmy.
There are apps that you can use that follow all posts with that one word in it, like liftoff. The lemmy dev was saying they were working on a tagging system, and I thought maybe that came out and I missed it.
