I want tutorials (Video and Web and/or PDF) , but also something like "toptwenty", a set of best-things-you-can-do with a NIT. Kind of "pearl"-specific tutorials.
I also believe that making content for some apps more readily available might help, too (Creative Commons stuff etc). I really like e.g. how Canola comes prepopulated or how the NITS include some images and music out of the box. This principle shoudl be extended, at least for content-related "pearls" or similar.
