What is Instagram? Number of photo sharing applications

What is the number Instagram of class Instagram sharing applications? Many people may have heard it had been confused by Facebook for $1 billion trillion in acquisitions, and Facebook, even if it was far away, was a lot more prestigious than Instagram. When you know that Instagram allows users to snap their own lives, select the filter style one-click to share to Instagram, Facebook, Twitter, and many people are starting to talk about what it's worth 1 billion dollars for a camera app that looks like a fool. Can such success be replicated at home? As I say, the discussion is not as practical as it is, so let's see if the domestic replicas have such potential that they can replicate Instagram's success. The use of photo sharing here is not necessarily limited to the Instagram very similar model, broadly speaking, as long as the function is similar to our income come in, after all, always look at a bunch of look different features no two replicas is also quite boring. And when it comes to sharing, an effective interaction with the picture is what we need, and it's not counted whether it's used directly to share it with Twitter.
