Let Snapchat be Snapchat, Twitter be Twitter, etc. The constant media frenzy over how fast everyone's growing and if they stop growing (aka Twitter) it's the end, just seems bonkers to me. The only reason for this rationale is Wall Street and public stock offerings. Twitter's stock price will sink if they don't continue a hyperbolic growth path. Never mind if the product is good, or if the existing users are happy. I would actually argue that Twitter's product has been floundering and its existing users feeling the blues BECAUSE of Twitter's need to drive growth. If Twitter had decided a couple of years ago to focus on making its existing userbase happy as well as third-party developers contributing to the capability of the network, Twitter would be in a stronger position today.
So I don't agree at all with the premise of this article. Facebook isn't "beating" anybody. If everyone suddenly leaves Snapchat and goes back to using only Facebook, that's not because Facebook is evil, it's because Snapchat looses its ability to develop products people want. If everyone suddenly leaves Twitter and goes back to only Facebook, that's Twitter's own fault, plain and simple.
