Pretty similar to you: Had heard about Mastodon when Twitter started imploding and made an account over there. But didn’t really get it and I never really used Twitter anyways so I wasn’t too interested in figuring it out.
Then when the APIpocalylse kicked off I came and checked out Lemmy and learned more about the Fediverse. When I found the Memmy app and more people started coming here it really felt like this was taking off, and I’m excited to see that momentum continuing. I haven’t opened Reddit since Apollo died, and this is now filling that void in my online diet.
