There are different ways to end up in the software libre community. I used debian at college but I really perferred windows at that time. Once I was working, I got in touch with free software again. I began to use it and promote it. It took me two more years to really understand, then truly believe, in what I was doing. A simple action convinced me that it is not just a matter of software, bussiness, community or innovation, but a matter of justice. It was reading a book.
My own red pill (remember Matrix) was Lawrence Lessig's book "Free Culture" (Cultura Libre in spanish). It is a must, It's easy to read and easy to understand but deals with really deep concepts and feelings.
Lawrence Lessig is giving a talk in Vitoria, Spain, next month. I've wanted to write this post to thank him for changing my little world.
Lawrence, you lost the battle, but we will win the war. ;)
