Open source and you

I love using, developing and (where I can) contributing to open source software. What about you? It has changed my entire outlook on life, the universe and everything. Okay, maybe not that far, but I believe it has changed the world and working with it has certainly made me a better developer. I believe we are only seeing the tip of the iceberg. It has grown to more than just software. Health, science, and geological industries, just to name a few, are all benefiting from the open source movement.

I would like to "open source" my experiences with this and for you to contribute your own.
