The first three people who answered the question to the contest won a Gmail account. I have more Gmail account invites so I will be running a similar contest weekly until I have no more left. So please check back!
The answer to the question was easy to find. Conduct a search on Google Dance Syndrome and the first result takes you to an article written by Danny Sullivan. In the article it reads:
Fair credit notice -- after writing this story offline while traveling, I thought I'd better check to see if anyone had already suggested Google Dance Syndrome as a term already before publishing. Not exactly, in terms of rank suffering. But as a physical ailment, a similar Google Syndrome was coined by WebmasterWorld member NGene in March to describe what happens to those who worry about Google so much. And on an adult webmaster board, there was a reference to Pre-mature Google Dance Syndrome for apparently worrying about when the Google Dance was about to begin, also in March. I don't want to link directly to that adult board, but the curious can follow this Google search to reach it. ).
The proper response would have been that the member "NGene" from WebmasterWorld came up with the phrase Google Dance Syndrome over at http://www.webmasterworld.com/forum3/10329.htm.
Congratulations to the winners and check back next week for a new chance to win a Gmail account. :)
