"There is such disagreement over whether Facebook is the next big thing on the Internet or whether it’s going to fail miserably.” Who are the people having this type of conversation? Why would a company like Facebook, with billions of dollars in revenue and hundreds of millions of users be on track towards "failing miserably"....Simply for being tied to a $100 billion valuation? Perhaps the valuation was lofty but I don't see a company like Facebook outright failing due to greedy investors.
