Ha yea ... the elephant in the room is that we probably just want to define ourselves as "Not-Mastodon".

Even though /kbin is a fusion of platform formats (which I think is awesome BTW), the underlying common factor is the primary basis of connecting or socialising.

IN the case of reddit/lemmy/kbin/link aggregators etc ... it's subject matters and interests, not direct person-to-person social connections (which aren't even possible on lemmy). It's a significant difference IMO, and well worth trying to package in a memorable catchphrase or term. I just don't know what it'd be (my best idea being "threadiverse", which doesn't capture this idea at all really).
