We have just begun an AgileBusiness yahoo group.
It is for product owners, business analysts and management folks. And anyone who cares about business (ok, that should mean all of you, I think). Including Govs, Non-Profits, etc.
A favorite topic of mine is Business Value Engineering.
Another topic right now: Scrum for Hardware product development (Embedded).
