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.
It’s true that you tend to be more tech literate if you choose Linux. However, it doesn’t mean you can’t be tech literate if you choose Windows or MacOS, which many Linux “advocates” seem to firmly believe. The same goes for “power users” arguments etc.
