Wow. I thought for sure that you had seen this!
I spent a few quality minutes looking at it this afternoon, and several pages came up in multiples, but you can minus (-) them out of the search parameters easily. When I got bored with it my search looked like this:
avantgo -socialdomain -jeopardy -livedaily -4thegame -spaceref -sports.com -itn
That brought it down to about 45k sites...still not too shabby.
I'll try and throw stuff at it over the next couple of days... and suggest others do the same. If nothing else, it is a good reference if someone knows there's a site interest they have.
