@tayledras I mainly use Libera, a backwater old fandom server, and one for a private torrent tracker. Most of the channels related to my sphere of interest (gentoo, various other software projects, networking, pleroma, baseball) all call Libera home.

In the past I spent a lot of time on Rizon, freenode (RIP), servers I can't even recall anymore... man I sat here trying to remember some of them too. Oh well, anyway.
