@humanetech Hi! Instances.social is the oldest instance picker, created and maintained by the admin of my Mastodon server :) I think it appeared even before Joinmastodon.org picker. The link to it used to be on fediverse.party, but at some point I removed it. TheKinrar mentioned the service might be closed in the future. I now returned it to /Mastodon website's page (at the bottom, Server lists).
There's a Wiki list of such services, I've updated it now:
