I've disabled adsense because it brings in like $0.60/wk. When I first got approved, it was like $8.00/day, but that slowly died down. Not sure why exactly. Adsense revenue isn't worth slowing down a site and angering users.
I think it might be worth it if you had a few projects all running Adsense, like 10 sites, or something. Correct me if I'm wrong?
