As I've mentioned in a previous Linux Line post, I am not a programmer. Yet Linux is built on the philosophical principle of freely sharing source code. This is how those who create Linux frequently advocate it.

But if I'm not a programmer, and source code therefore means little to me, why do I use Linux? Why do I spend much of my time suggesting others use it? Is it just because it's available fore free? (Spoiler: No.) These are interesting questions that are not discussed very often.
