I was wondering the same as you and found this article from DN Journal a few days ago. It once sold for 9K at TRAFFIC in Vancouver on June 9th, 2010 (see the very last screenshot). The domain doesn't appear to have ever dropped either, so i'm not sure how it sold for so cheap on Flippa... but maybe it was an auction gone-wrong type of scenario?
I included a few extra screenshots from the article, since I found them interesting, and you can read the entire thing at this link:
