More Ads at Google's Search Results Page

A thread at Search Engine Watch forums named 3 Ads at top of Listings reports that Google is now testing adding an additional top AdWords ad at the top of the results. Currently there are two results in the top sponsored area, but according to the AdWordsRep, they are testing "stuff from time to time." AdWordsRep clarifies that "Probably only a few folks will see it, and then not for long. It's not a permanent change."
