Edit: As @habnab has pointed out, my numbers may be misleading, rendering my stance pretty useless, haha
I actually was thinking the opposite. kbin.social had more users than all of lemmy combined ^1-- I think my concern is more that the rest of the fediverse is going to look too quiet because kbin.social isn't federating right now. Couple that with the technical issues here at kbin.social (that seem mostly resolved right now) and it could turn someone off to the fediverse.
