I usually don't poo-poo acquisitions but this one surprises me for a) the valuation (Facebook really couldn't convince them to exit for 5 or 10 billion?) and b) Facebook really needs to demonstrate that it can get into these markets itself.
With all the supposed ingenuity, developer talent, money and existing users, why can't Facebook build anything besides a news feed?
I personally think Facebook Messenger is better than Whatsapp, and you can easily upgrade to a private group when appropriate. Whatsapp seemed to miss the ball on tablets/everywhere by focusing only on phones and requiring a phone number, which obviously worked for them but I think Facebook's product is better.
