Yep, same here. A couple of subs I followed mentioned Lemmy explicitly so I gave it a look. Lemmy.world seemed the most active at the time so I joined here.
Same. The fact that Lemmy has several iOS apps also sealed the deal, as I do almost all my browsing on mobile. I made an account on KBin at the same time, and an eagerly watching both to see how they develop, but Lemmy just has more to offer right now.
