Those ads are there because those vendors paid for the privilege for their ads to be displayed in those slots. I don't think you're going to have much success dictating where those paying ads go, unless you're willing to pay not to see them or you want to help poser vendors pay to get advertising on this site. That would be the solution to your complaint, but not how to get more content... nor is complaining about who posts where, all that's going to do is earn a thread lock, so I'd let that go as well.
