Yes, UI has to be totally intuitive!
If you had discreet event-driven notifications (NOT like that awful paperclip that MS Word had) that give you the right information at the right time, would that be useful?
Assuming you could turn them all off if you wanted.
You mean like the guided tours that 'patio11 made a video about that I watched recently? :P (I recommend the http://www.kalzumeus.com/ mailing list if you haven't seen it yet)
