Maybe I am part of that new group? I'm just here for the memes. Lemmy is amusement for me and a way to kill some time. If I want to have deep or meaningful discussions I'll talk to people I actually know (and then I'll also know I'm not wasting my time arguing with a troll). The "casual browsing" content is also lower quality here than on Reddit, but I can't complain, because I don't really contribute, I just lurk.
