Have you seen it yet, the rectangles (728 * 90) that have two little arrows and the viewer can scroll through many pages worth of adverts. I haven't got a screenshot of it at the moment as my site isn't seeming to bring any up.
^^ Yes, actually, it is new. It is something they are experimenting with. SoftCloud, I think it is pretty cool too.
its the same as before, but not instead of clicking where it says 'display more ads' you click the arrow. It does look cleaner though.
