I took the best 6 minutes out of a presentation that Fred Brock of Jive Software delivered to our engineering teams to teach all of us about the best ways to develop widgets for Clearspace 2.0. This is a must-see for anyone wanting to write widgets for Clearspace 2.0! I've also attached a PDF version of the slides from Fred's presentation.
