What surprises me about the Google attitude is that it seems to go against one of the basic rules of entrepreneurship: that it's the execution that counts, not the idea. In other words Google seems to throw multiple ideas hoping for some to be successful, but doesn't really seem to put an effort to push them forward despite the initial difficulties. It's a fundamentally insecure attitude: they hope to be blown by the success of something rather than working hard to make it succeed.
