Pace of Progressive UI

Our most likely audience is busy, productivity driven people so aside from testing what the minimum UI is to keep them interested, the _pace_ of the revelation of that UI will need to be exhaustively tested too.

There's an argument for helping people to slow down and take a minute from the beginning but they may benefit more from being able to start using the app relatively quickly and using other points in the app to teach the art of slowing down rather than them ending up frustrated with their initial experience.
