Ever since I've decided to become a coder, I couldn't get enough of that open-source spirit (it's just like Christmas, but for programmers). I use something, find a bug, report it, and usually establish a very friendly communication with the developer. That's I think more important in an open-source project than what most people say. It's not about some big company getting that new Linux server (sure, that's important, too), but the way people interact, freely, sharing code, opinions, and experiences. That's the essence of open-source — it puts open in open-source.
