Gamification and Communities of Practice

I was recently looking at the concept FavorTree (now discontinued unfortunately) which was a mobile gamification app designed to display the good work any person was doing within the neighbourhood.

Lend out your ladder or teach someone how to unblock a drain and you would see your virtual ‘tree’ gaining fruit.

It immediately reminded me of a Community of Practice (CoP) called Fiery Spirits (http://vimeo.com/16024731) which connects people who have a shared interest in making a difference in rural communities.

I was wondering if anyone has combined Gamification within a CoP, in the case of Fiery Spirits, to better reach out to younger members of the community and promote the idea of being a good neighbour, sharing and learning together.
