This is actually a really cool idea, like I'm kind of obsessed with the idea of using custom attributes / aspect oriented programming using C#. I don't expect to ever be contacted by a recruiter for purely that fact... but if they saw my code... they might. That's cool.

On the other hand, i'm more of a consumer of open source software than a producer. I tried submitting a pull request once, it got rejected, and I decided it wasn't worth the time.
