I’m on two, this and sopuli.xyz - which I joined on a whim before even knowing what lemmy was. I’m pretty sure my personal statement was merely “I miss usenet”. And, it’s weird, but the community search function is…inconsistent at best. I’ve tried searches on three different instances for a common term and come up with nothing (sopuli), 4 communities (.world), and 6 communities (.ml). .world seems like a more generic fit and, um, yeah - no personal statement.
