Actually everyone I use to know from Digg (the front page makers) are mostly into StumbleUpon rather than Reddit. I also have another friend from my Digg days who built up his Facebook page via ads and that gives his blog quite a few page views. But i don't really see many folks trying to push content on reddit — the front page is off limits so you're stuck with the sub-reddits (which can be good but they can also be a waste of time). I don't have any good numbers on reddit or Twitter because I haven't really pushed stuff there for quite some time (so sorry if this didn't help you much).
