The downside for you and me is that the ads get served up r e a l l y s l o w l y, almost to the point of ridiculous.
So! For now, I've put the ads into iframes, so they'll get served up last. But! Being the half-smart guy that I am, I only kinda-sorta remember how to use iframes, so they're positioned down ten pixels and over ten pixels and regardless it is what it is. :)
