I dialed in crazy on one single component of a large Open Source project, and at some point......I was the expert. I didn't understand everything in the project, and I didn't know near as much as most people, but for one tiny component, I couldn't find someone to answer my questions on and I became the one people went to for questions. It kind of puts into perspective how software works.
