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.
Make sure you’re following hashtags on Mastodon. I see plenty of people posting stuff like art, food and gaming opinions because I’m following a bunch of topics that interest me.
When it comes to Linux, it’s only natural that FOSS people are more interested in the fediverse than the average normie, because that’s where all of this stuff came from. I know FOSS people who have been using Mastodon for years and years.
