Fosstodon.org is great as well as techhub.social if you’re looking for good servers related to tech. I use fediscience.org as my server though, its more up my alley plus I can still access fosstodon and techhub.
It’s more closely related to the initial intentions of the internet than most other social platforms. Ideally it could get things going back in the right direction again iif nothing else!
