The word on the street is that Facebook tried to buy popular self-destructing messaging app Snapchat. Only after Snapchat refused to be acquired, Facebook decided to clone the app and launch a competitor. They did it in just 12 days. Only one day after launch, Facebook’s Poke app is the #2 free app in the App Store. SnapChat is #8. The message from Facebook is clear: either you’re with us, or we’ll bury you. And fast.
