I'm seeing from friends who admin Mastodon instances that the big public instances are having yet another mega-spike in new user signups.
Of course, #SignsAndCodes is still its little ol' cozy self and always will be. Everything is easier when you only have a handful of personal friends as the regular users.
But bless those folks on the mega-servers. I don't know how they're keeping everything up and keeping their sanity.
