RE:What's App? $16 Billionputting such a high price tag on a messaging app is insane. First off the app is free, no ad revenue, 400 million users even if the app is $2 in the future. That still does not justify a $16 billion valuation. What will the bbm app be worth then, more than the market cap currently? lol Even if they start to charge for the app no one will use it and just change to another free app or bbm messenger. Even is they start with ad revuene. People will change to bbm because no one likes the disruption of ads.
