So far I think of Pollen like a Lego set. It has a picture of a nice website on the box (http://practicaltypography.com), and all the pieces. But unlike a normal Lego set, the instructions tell you A) how great Legos are because you can build anything you want, and B) how to connect two or three individual legos.
I'm not saying Pollen should include complete instructions to replicate the Practical Typography website, and the documentation does do an admirable job of explaining the very basics. But ideally it would include complete instructions to replicate something approaching the functionality of a modern CMS. The step-by-step instructions included with Legos don't limit you from building other things, they don't lessen the flexibility of the system; they just make it easier to learn by doing.
