When I visited Super User this morning, an extra spurious blank space appeared at the top of the list of questions on the home page.

This blank space doesn't appear on any other SE site that I've visited this morning, and did not appear last night.

My environment is: Chrome 22, with Adblock Plus and NotScripts extensions; Windows 8
