I ran across this the other day:
Open Source.com: How to become an amazing contributor (to an open source project)
I would love to be one of those people in the story. Being amazing is always a good thing. Actually, one of the things that stood out to me was that this is a two way street. The author was lauding these people, but at the same time, they commented on how it was easy to contribute. They found documentation that helped. The code was structured in a way that made hacking easier. I think both the contributor and contributee are amazing.
