  I just switched ad servers on my urlLink Banned Music web site -- the previous ad provider was pushing a lot of online casinos, debt consolidation, and "hit the monkey and win a prize" ads.
The Google Ads are a bit more to my liking--they are just text--no pop-ups, warnings, sleazy pitches, etc... I don't make a lot of money off these ads. In fact, they just about break even for all the costs associated with ericnuzum.com.
Google tries to target the ad content to the content of the site. The funniest thing is that the ad servers picked up on the following item on the page: Marilyn Manson banned from Six Flags Management of the Six Flags Amusement Park in Darien Lakes, New York, bans Marilyn Manson from performing at the park as part of the Ozzfest tour. No other acts are removed from the bill. The "targeted" ads Google is offering? Six Flags tickets. I guess Google's servers don't have irony algorithms.
