@dublinux Not many, I looked at a few where I follow others but several were either not accepting new users or needed me to request an invite from an existing user, others were too big (difficult to moderate, generally)

This Mastodon instance is for people interested in technology. Discussions aren't limited to technology, because tech folks shouldn't be limited to technology either!
