The FireChat Post

FireChat became famous due to its mesh networking function that allowed Hong Kong protestors to connect with each other when the mobile network wouldn’t support their discussions. The clever underlying technology belies the key consumer benefit of a messenger application.
Why it's a feature not an app
I logged into FireChat for the time in a while the other day, as I was in two minds to keep the app on my phone as part of my occasional spring cleaning process. I got confronted with the screen shot above. The mesh network technology was very interesting with some largely niche use cases unlikely to drive large adoption of the app. In order for FireChat to get an audience, it has to piggyback on Twitter or Weibo – which delegates it to just becoming a feature rather than a product in its own right.
