What happens when students create their own collaboration tools?

Gigaom: "I teach technology and innovation to working professional MBA students who are changing courses and teams every ten weeks. Collaboration tools are critical to our effectiveness. Over the last two years, my courses haveserved as testing grounds for two locally-grown, student-designed tools: Acceledge and Piazza. These tools, as well as other student-built offerings, such as Coursekit, are the result of a growing student frustration with “old-school” collaboration."
