What's happening? What's up? What that means is not always clear Does the initiator want an answer? These phrases can mean something or nothing at the same time. Either one of these can be a substitute for hello without the expectation of getting a thoughtful, informative answer or the precursor to a long discussion of what is going on in life and the world. It can be narrow in scope or broad.

Is it about you only? Is it about family and friends or work? How about the world? 

The idea of the "cool waffle" came from friends and colleagues having a great conversation. The "cool waffle" was never boring and topics were fresh. The discussion could be about culture and entertainment, sports, life, health, etc. So hopefully with the content presented, Coolwaffle achieves that goal.
