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.
I hadn’t even heard of it!
Same. Googled “Reddit alternatives” on the first day of the blackout and just signed up to 4 or 5 to try. Lemmy and Kbin were two.
