Take a look a this folks, good ole ShoeMoney is at it again http://www.webpronews.com/topnews/topnews/wpn-60-20060419GoogleMediaBotIndexesWebPages.html But wait, Jensense is there too!
Its actually not and I am going to do a clarification on all the new big daddy "features" as soon as matt sends me his slides. I do not want to misquote them. Basically thought its like this. If your page is about to be indexed by googlebot it will check first to see if media bot has already been there... if it has then it will use mediabots cache... otherwise it sends googlebot. There is no advantage. I hope that makes more sense
