I don't know when it began, but I stopped using the address bar quite some time ago. I found it easier to type in the url into Google. If I make a typo, it offers a correction, and I don't accidentally end up whitehouse.com, if you know what I mean.<p>That said, I don't think people are searching for "search engines" on Google. I think people are like me in that they use Google as an address bar.
