I only have the same issue with Mastadon that I do with Lemmy, I have no idea what instance to join. This one I'm apart of now for Lemmy I randomly joined when the admin said he'd accept reddit refugees who wanted to try out Lemmy.

If anyone has any suggestions for good instances to pick I'd give Mastadon a try. Otherwise, it's a nightmare for people like me (who's been compared to Chidi from The Good Place in terms of my overthinking and decision making).
