Add to that, there's a popup asking for my email address for their mailing list as soon as I start to scroll. Seriously, has anyone ever entered their email address in order to get rid of a popup instead of clicking "X"? Is there a more sinister purpose to these boxes? I note that users without Nuke Anything (or similar) installed in their browser will have to click whatever button the designer chose, and its associated tracking code, to close the popup.
