Read this blog post by Janetti Chon to learn more about each track of this year's expo.  They are:

• Strategy and business models
• Marketing and community
• Design and user experience
• Fundamentals
• Development
• Web operations
• Mobile
• Security
• Web 2.0 at work
• Government 2.0

Right now, I'm most interested in the design and user experience and government tracks.  My ticket gives me two tracks, so I'll decide closer to the conference.  One of the keynotes I plan to attend is about tech gear.  Patrick Norton and Veronica Belmont of Tekzilla will deliver a review of the latest gear plus tips on how to improve the stuff we own already.  This one is happening on Thursday, April 1 at 3:30.
