ExoClick Questions

I recently signed up with ExoClick because the big G terminated my account over a year ago, I haven’t been happy with AdBrite, and Chitika has decent payout per click, but I guess their ad layout just doesn’t appeal to people, because I don’t get many clicks.
My question is, what categories, other than "adult" has the largest variety of ads? No matter what I choose, I seem to get the same two advertisements just with different keywords. "KEYWORD at netster" and "KEYWORD information" are just about the only two ads that they seem to serve. Oddly, I’m still getting clicks at about $.01-.02 a click, but variety would certainly help. Has anyone been using them for longer than a few days and can help me out?
