I would add ZPT, skins and increasingly formlib to the list of things to
learn. +1 on demos vs. tutorials. A good working demo functions as both a
tutorial and a testimonial.
I think right off the bat, the bookmarker app should be incrementally
expanded. Evolving the app *is* the power of Zope3.
Other apps that start off easy but can grow increasinly complex fast.
I've been wanting to put together a Concept Map companion to the Bookmarker
tutorial. If anyone is interested in helping out please give me a buzz, and
I'll setup a collaborative concept map.
