I've seen it on occasion. Not as common as the main ones, but it's pretty good. I like Megaupload, myself, but international downloaders don't like it because it likes to limit people's countries downloads and such. I get my full 300 kb/s from Megaupload, though. Unlike rapidshit. I rarely get better than about 150 kb/s from rapidshit, plus, their site just sucks.
