Why successful messaging apps are so scarce..

the most important feature of any messaging service is whether or not your friends are on it: if they are, your service can be very barebones (like WhatsApp), or technologically weak (like LINE, in my estimation), and it won’t really matter; however, if you’re friends are not on it, your service can be super full-featured and highly-differentiated (again, like LINE) and it won’t matter. The trick is to not just add users, but to add users by group, so that they have a reason to use the app from day one.
