In the US maybe. But there are markets where Google wishes they could even establish a foothold, much less a beach head.
IT madness, Ive got a site that is 4th in Bing for a quite competitive keyword and gets practically zero traffic, the same keyword is 186th in google. Ive got a few sites riding high in bing, but wondering if its more geo location than anything, its giving preference to sites whose ip is near to you, which would explain why lots of sites of mine are doing well in search terms, although not in traffic, i think if Bing grows then I would prefer it to Google, If my theory is right then its much fairer,
