This would be fantastic!

In fact, we were going to build it ourselves or use GetSatisfaction as they have this as core to their product. Obviously you can't compare the two, but in my opinion this is the last missing piece in creating a True User Community. Our greatest assets, like Zendesk's, are our amazing customers who truly want to help each other.
