Was looking for a furry one, and pawb.social seemed to be well-run (since it was related to a couple of decently-sized Mastodon servers) and was generic enough (and not NSFW focused). There also seemed to be a decent number of technical people there as well (in fact, one of the Mastodon instances is furry.engineer), so it matched up with my other interests as well. I considered lemmyrs.org, but ended up not choosing it.
