Before the whole Reddit migration I was passively aware of the Fediverse, I thought I somewhat grasped the concept, and had created a Mastodon account, but never really used it.
But once the migration started, I decided to try out Kbin, and really liked it, and even started to use Mastodon more often.
For the last year or so I’ve been using a private PeerTube instance I run to host videos my kids like to make and share with their friends/family. It isn’t federated for privacy reasons.
