Lemmy and Mastodon. Only lemmy really interests me. I got pixelfed and bookwyrm too, the latter seems pretty good replacement for good reads. I don’t see myself posting just to myself on pixelfed. I also find mastodon very difficult if you don’t want to talk about Linux or American politics. I absolutely do not get the point of friendica and think the low MAU shows that no one wants Facebook 2.0
