Do you have a wishlist of all the problem domains you'd like to tackle? (I'm thinking web, mobile, and desktop applications above the system level when I ask this, but any other areas are wonderful. Databases. etc.)
We prefer to keep things a pleasant surprise, but we'll be emailing anyone who signs up with a suggested reading list if they want to start brushing up on old skills or acquiring new ones to get ready for launch day. The reading list will give a good deal of direction.
