not sure.. but that big gap up at 600 will need to get filled eventually. I think Google got its challenges - the biggest from Facebook and other social media companies. I don't know anyone goes to Google for find what's a good place to eat around you. People use Yelp, UrbanSpoon, or Facebook. Google is a great search engine tool. This is also where the problem is. They don't control content. A big enough content provide can squeeze them out. Plan to get on the bandwagon for FB whenever they come out. That will be a phat IPO.
