Google's AdSense description promises ads that are "relevant to your audience and your site content—ads so well-matched, in fact, that your readers will actually find them useful."

Someone within the aforementioned discussion sent a complaint to Google about these ads, and they were taken off the site within thirty minutes.

Looks like there was lots of coverage on this yesterday.
