Facebook is just a one trick pony – that just does one thing beautifully – that is Social Networking. Google does that and also so many other things such as search, email, maps and so on. Microsoft even provides virtual labs where huge communities of developers get trained to use its technologies for free. And yet all these companies need fewer computers than Facebook – which means the costs for Facebook are much higher. Facebook attributes it to the higher level of engagement of its users – but does that higher level of engagement proportionally add to its revenue? Judge by yourself weather facebook IPO is scam or not."
