The Reddit-inspired instances like the Mbin and Lemmy-based ones may be of interest for you. The Lemmy ones, from what I can tell, always hide the follower list, and the Mbin ones allow the user to choose between showing and not showing. Also, both seem to be able to connect to Twitter-like instances, though UI for that part in the Mbin ones is pretty barebones and the Lemmy ones mix them up.
I see. That’s sad. But thanks for clarifying it!
