I am working on a new project called Coinjars which is social media currency for Facebook. You can sign up for free under applications in Facebook. If you add an account, I will send you some a penny so you can see it really works.
The facebook is just one application. We are working with a few non-profits and other organizations to teach them how they might use this. We will be creating marketing around this area.
