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!

Modern PHP is supposed to be a decent language these days rather than a collection of footguns so I wouldn’t write it off out of hand. It wouldn’t be my first choice of language but it still runs huge swathes of the web, interesting choice for a greenfield project though. What it will mean is it’ll be harder for Kbin to attract developers on a voluntary basis I think, if I’m giving my time for free I’d personally much rather spend it writing Rust than PHP even if PHP is decent these days.
