In the inline style tag right before the ads, there's a reference to http://2.afs.googleadservices.com/images/partners/COi4yqbh-p0CFQJciAodOTAbrQ/kosmix.png which is the "Sponsored Links" image. This strongly suggests that Kosmix and Google are working together to provide these links. Given that, there's nothing too weird about this.
