I noticed that on the right as you scroll down the page a section including some adsense links "suggestions" floats beside the top right of the browser window dynamically as you scroll down, but there's this long blank space unused. Have you guys thought about just floating that entire right side column (with the author specs, adsense block and the one that's floating currently, instead of just that one section?
This would move the adsense block which may raise CTR, I figure if the 3 links are allowed to float without breaking any rules with adsense why not the block too (with the author specs as well). This would also give people a quick way to email the author, friend them if they get half way through and want to friend them (without scrolling back up) or have a question they want to private msg the author about and again it may raise CTR on the adsense block.
