Looks like KBin has an edge over Lemmy now in terms of monthly active users.
It's obviously a pretty silly thing, and is not in any way indicative of which project is "better" or more "long-term viable" or anything — instances of both federate with one another, and with the rest of fedi, so it's all one happy family.
That said, it's notable. KBin is a relative newcomer to the "Reddit-like fedi instance" game, and also does not have the tankie baggage.
Anyway, the more, the merrier!

Huh. That's surprising. I just joined https://fedia.io/m/cybersecurity from my Lemmy account on szmer.info.
Did you find it by searching for !cybersecurity@fedia.io on your instance?
Edit: Interestingly, I was eventually able to join Kbit magazines by pasting the full URL into the search - it seems like this works but using the ! format doesn't, at least on my server.
