Yeah, I've heard several people complain about the meme communities. There are a few that post lots of stuff and overshadow the real stuff. If you don't happen to find out how to do it, I can understand why you'd be annoyed and not join Lemmy.
But I was talking more about low quality content like writing a cheap joke that is very obvious. Or being the 10th person to just agree in slightly different words instead of upvoting the first comment. Or having meaningless arguments. I kinda do all of that. But it's more a social media thing and wasted time, than something advancing society or my own life.
And some other people just write 5 comments a month in topics they really know something about, and use their spare time to read the remaining Terry Pratchett novels instead.
