Its crazy how all the search engines return the results. Obviously Yahoo! is better for the amount of resources on a term as they still regard nofollow links.
Search engine breakdown:
Alexa =
15,359
Google =
613,000
Yahoo! =
2,370,000 (different results completely)
Live =
433,000 (digital point member- seocontest2008 is top)
Ask.com =
