I didn't have time to read though all comments, however, it appears to me that Google has a very strong and unique culture that is often credited for contributing heavily to the company's success. How does this factor into the why aren't there more Googles question? I don't hear the same things about Facebook so I wonder if in 10 years will they still be mentioned or spoken about in the same vein? In any case, the reason I mention this is because it seems like a very difficult part of a company to place a value upon. Perhaps this is why "Googles" escape acquisition...
