Cool, yeah I'm obviously not a designer either :) It would be something to work on if this ever moves forward. As for the blank ad - that's a strange problem! What operating system are you using? It worked fine with everything I tested, including Chrome on Windows. Do you have any plugins on? It should work without it, but do you have javascript enabled?

And yeah, I understand what you mean. I would build a sort of "ad marketplace" for advertisers that allowed them to sort ad spaces however they want if there is enough interest.
