Actually they told me that they were getting __too many__ clicks, so I'm sorry but it wasn't your ads blocks that ruined me! ~~laugh~~ 

I don't think Adsense is the less intrusive ads service, there's a new one called {link:IntelliTXT|url=http://www.vibrantmedia.com/|newWindow=true}, it identifies relevant words and double underlines them, when you put your mouse over such word it shows up a div with the ad. It's pretty neat! So mainly it's actually inline ads that only show up if you go to the word that is smart tagged.

At least in my opinion that's less intrusive! Although they are not yet worldwide nor for everyone, if you read their {link: qualification policy|url=http://www.vibrantmedia.com/site2005/WEB_02C.HTML|newWindow=true} you'll realize that.
