Hey, great job!
A real test of an idea could often be it's potential to generate revenue.
I understand that it is a side-project and you may have different motivations.
But I guess it is even more reasonable for you to try implementing a business model.
There is not much to lose (given you don't end up putting desperate adverts all over the app... Duh!)
As an example, the 'karma-as-commodity' model might just work.
Point here being that I don't see something as valuable to a potential employer as a person who can write amazing apps and make some solid money out of it.
