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.
Twitter was designed to be addictive, whereas Mastodon was specifically designed to not be addictive. That’s why scrolling Mastodon feels so boring after a while.
