Congratulations Facebook (opens in new tab)

Regardless, I'm pointing out the effect that just adding a couple more points will significantly increase the results. This is more-so a proof that the example is not significant because of the variance of adding another term. Good point, though.

A surprisingly large number of people always use their favorite search engine to get to other sites. They Google for "facebook" or "www.facebook.com". This goes for all web sites.

I think some of this is driven from the google toolbar, which many people confuse with the address bar.

On a side note, what really boggles the mind is the number of searches for "google" or "google.com". According to the Keyword Tool, there were approximately 30mil exact searches for "google", and 7.4mil searches for "google.com"!

A lot of people use google instead of typing in URLs. So to get to facebook, people go to google, then type in facebook or facebook.com, and then go from there.
