@kissane I definitely feel #2. It was why, during the initial surge of new users in 2017, I gave up on the ‘verse. I (an autistic person) have relatively niche interests that only have a robustly-sized fediverse community amongst Japanese users, and I only know very basic Japanese.
I also just don’t like having an immutable username and having to make an entirely new account to change usernames. Other people, especially trans folks, have voiced the same concern.
