True! In the book 'The Lean Startup' by Eric Ries, he actually had the same idea for a growth strategy for his messaging platform IMVU. It is not a new concept.

The idea is this breaks down the barrier to entry to start incorporating multiple unifications. For example, we start with messaging and next we unify emails. From there we unify live streaming, and then something else. I am not saying these are the things we are going to go on to unify, but that is the concept.
