What about including a short Most Wanted list of examples and exercises to get people going.  We could even offer a bounty! (read: mug, t-shirt, badge, kudos). 

I say this because as it stands, it seems hard to know how to start on something this big (even though exercises can be short).  Perhaps expanding this into more of a short HOWTO, and/or add "If you think you'd like to start on a lesson or example, drop us a line on our [discussion list](link) and we'll help you brainstorm"
