Interest and Open source

One of the great things about open source software is, of course, the fact that anyone can participate, so the pool of resources is limited not by an annual hiring budget, but by interest in the project. That means you can have any number of developers, but it also means that one person may be involved in several areas if he or she finds them interesting.
