Definitely not buying FB at this price, but the only argument I can see justifying the price is as more a long term valuation of them as a tech company. In other words, in the same way the Google is clearly no longer "just" a search engine, FB has the talent and resources necessary to be more than a social network. That's definitely a gamble on valuation, but I can vaguely see someone justifying the price in that respect.
