Large Rectangle & Collapsing Ad Units

I made two changes to my AdSense setup here today. First, I added a large rectangle to the footer. This should give you some links of interest when viewing any page of the blog. I also put this unit in its own custom channel, so I can see its effects separately. Second, I made all of the ad units collapsable, so that you don’t see any gaping whitespace when there aren’t any ads to show. Let’s see how this affects things.
