stimw personally this extension is one that I am most excited about. I'm still on beta 15 as I have just a couple dependencies left so I haven't had a chance to use it, however we have some early plans to make this our primary solution to track and reward users in our community as part of our incentive model. I think the extension is very powerful and it will only become more so over time as more extensions integrate with it, askvortsov has also alluded to some future features related to metrics which would help with all of this.
So that means things like giving badges based on certain actions, assigning an experience/activity level either through a group or badge, and eventually tracking points/karma score for all users and rewarding them.
The saying goes, build it and they will come 🙂
