The Flexibility of Open Source
One of the things that has been a strong point of Open Source Software (OSS) for years, even if it hasn't been held at the forefront of the battle, is the flexibility that OSS offers. This is something I think needs to be said more these days as our world becomes ever more dynamic, requiring software to be ever more flexible in order to keep up with our ever changing lives.
One recent example of this flexibility at work is with the announcement that Linux isn't Y2K(38) compatible. As of right now this is a non-issue as 64 bit Linux will resolve this completely by the time it actually becomes an issue. However, it wasn't too long ago that simple natural software advancement was the cure for a problem.
Almost everyone alive today can remember the huge issues presented to the world in general, and not just the OSS community, by the Y2K bug.
