I was checking stats today, and found something interesting, related to my wiki site, www.wikilookup.info.

I found that I have a few pages for which I cannot explain why they show up first in google ranking.
It appears to be an authority page in Google. These pages appear to have no google page rank.

Note: it is a copy of a wikipedia page, yet it ranks number 1 for a few terms.

such as:
woodrow wilson birthplace
when was woodrow wilson born

http://www.google.com/search?q=when+was+woodrow+wilson+born&sourceid=navclient-ff&ie=UTF-8&rlz=1B3GGGL_enUS247US247

or
how old is walter cronkite
http://www.google.com/search?num=100&hl=en&newwindow=1&rlz=1B3GGGL_enUS247US247&q=how+old+is+walter+cronkite&btnG=Search

What do you think it means?
