I was browsing SO today when I stumbled across these two questions:
So, both questions are closed.* The problem? Each questions is closed as a duplicate of the other; within one minute of each other (they were both closed "8 minutes ago" when I first checked).
Can we add a feature to detect this and prevent a circular Close as Duplicate like this?
Better yet, prevent newer questions than the current one from showing up in the Close as Duplicate list.
*As of 2010/06/17 18:32 UTC the first question is now reopened and the second deleted.
