This is a bit off topic but I thought I'd share. I was looking at a blog today and saw the categories in the sidebar. It was a Disney and Orlando site. After a few lines of "hotels" "rental cars" and so on, I noticed the rest of the links looked a bit different.
I then noticed that the guy had made his adsense code colors and font blend in with his category text. So the links that said "disney" orlando" and so on was actually google adsense links!
I thought that was pretty clever, I bet he gets lots of clicks that way.
