I placed a search term into Google and Cuil.  The exact same term.  One with relatively predictable results.  The term I used is the title of the post below this one.

This must have been tough to explain

Here are screen shots of the results.

Google:  First on the list

Cuil:  Nothing found

See for yourself.  Click the graphic and a new window/tab will open with the full size capture.

Cuil is slow and the results are, when you get them, completely irrelevant.
