Zuck should probably be fired (gracefully step-aside, courtesy of shareholder activist pressure, given his voting control) when Facebook is forced to do a $16 billion write-down on this. WhatsApp won't even be worth the cash they're paying for it when the music stops. They just bought today's version of ICQ for $19 billion. This acquisition leads me to believe Facebook is most similar to Yahoo at the peak of the dotcom bubble (the acquisition strategy, the massive overvaluation, the weak advertising platform). Yahoo was a portal, Facebook is the same premise but in social networking (the all-in-one champ). There will probably be pieces that spin out of the social networking scene that end up producing the next Google, while FB languishes as the new Yahoo.
