Exactly. An app should NOT be allowed to move from development to extras unless:
1) the description of what the application does is clear and non-technical so that newcomers and average joe's and jill's can understand what the heck its about
2) there is a short help/tutorial section built into the app or at the very least provided as part of the application description in the downloads section.

Are these not requirements in the Maemo style guide (or whatever its called), by the way?!?
