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.
Already used Mastodon before and understood the concept of decentralization. I used Lemmy years ago, but the front page was getting like 12 upvotes so not much was going on lol.
