I challenge you to do a search on Google and find a page without Wikipedia as one of the top 10 results.  OK, it's not that hard, but it is getting more difficult.  After reading about Knol, and perusing a few other blog posts about it, I decided to try some random searches on the big G and found had a first page result with Wikipedia.

Almost all pages now have what I call a GWikiRank.

A few examples. 

To quote Riley from National Treasure:
Snorkel: Rank 2 (2nd result)
Albuquerque: Rank 4 (4th result not including the maplet at the top)

Highly scientific terms seem to have high GWikiRanks:
Photosynthesis
macular degeneration

OK, pageranks for sports sites must lower the GWikirank a bit:
Tony Romo (1)
Tom Brady (1)
Kurt Shilling (3)
Barry Bonds (2)

Large companies:
Coke (3)
Microsoft (4)
Even Google (19)

It's no wonder Google is seeking to subplant Wikipedia
It's gotta be irking Google that Wikipedia sticks it's nose in almost every search result.  Some are speculating Google will eventually kick Wikipedia out of results.  That would be MOST EVIL.
