>In what circumstances would this be useful?
After the Panda virus decimated my sites, I started wondering if my most important pages were even visible any more to Googlebot, so to put those questions to rest, I used this tool. When each page came back with "Success", I could at least rest assured that I had not fallen into the Googlevoid. For that reason alone it was time well spent one night.
