I think lain chan is sort of an anti-meme imageboard. While they're ok here and there, when you get to much of that, you end up with loads of memesters and quality of discussion goes way down hill.
Look at /cyber/ over on 8chan, for example. All it is is just a bunch of glitterboys talking about what's "schway", and posting their glitterboy punk guy over and over. /cyber/ blows, here we get some real discussion, it's way better. I think if you want memes, go to cyber, or go just anywhere else.
