I’ve spent much of the last 3 days on there – its really good although in comparison to Twitter very “right on” and tech focused, with the politicians, preachers and marketing lot all strongly discouraged.
hard to describe what it is like; maybe a combination of 1980s era viewdata/BBS culture mixed in with the web 2,0 stuff like Deviantart, reddit etc but with more grown ups and people actually being decent to one another (its more about the social bit than trying to get free downloads or anything like that but there is a lot of interesting content being posted)
Be aware a lot of the “federated” timeline (the one which contains all the instances) will be in French, German and other languages (as the French and Germans built a lot of the network and instances, most likely inspired by their Minitel and BTX systems).
Also choosing an instance takes a bit of forethought, you want to pick one that isn’t overloaded (two of the main ones have already stopped accepting users) and that federates with enough of the others if you want your messages to be seen by more people.
