I'm thinking a bit about social media today because as much as I loathe failbook, I am deriving nonzero value lately from groups about issues like ADHD and ASD, and I am getting the sense that this is partly due to how they function in ways which the twitter-like microblogging format and the reddit-like threadiverse format do not.
now to be fair, the threadiverse is smaller and newer to an extent that groups there just haven't evolved to the point where they reach full potential diversity, and that may have a lot to do with it.
however, comparing the availability and discoverability of neurodivergence groups on reddit to that on facebook, I would say FB has it better, and in a more user-friendly format. at least when it comes to well-moderated FB groups, which is key. the poorly-moderated ones are absolutely horrendous.
I haven't been looking to replicate a FB-like experience on federated social media since long before I was on what I consider "fedi" - so, since Diaspora was still a network anyone talked about in the present tense - so the only ActivityPub FB-like I'm aware of is Friendica. are there others?
what I *really* wonder is if a FB Groups workalike could gracefully degrade well enough on *both* microblogging fedi and threaded fedi to be useful in those formats, plus stand on its own… 
@deutrino@mstdn.io I'm keeping an eye on Fedibook which started up recently as a FB/Friendica alternative. I don't know too much about it just yet, but it does have a clean modern UI to it already.

@keshara thank you! I'd never heard of this one!
