Normally I don't like ginormous ads, but Amazon had a 300 x 600 summer display ad that fit very nicely on the sidebar of a really really long page; did quite well. I admit I could find a use for one if they had one. I have a lot of really long pages, and I don't mind putting a few more (or bigger) ads on them.
But like I said, as soon as they do some idjits would slap three of them in a row above the fold on their WordPress site and drive fake traffic to it all day long.
