Adventures in Open Source
2007

Abstract:

Open source software development is not just about providing the source code for your application. It is much more about building a community around a shared project. That takes time. I think the biggest myth about open source software is that you say 'hey, I'm open source now' and suddenly thousands of qualified people give up nights and weekends to work on your code.
