To me this is at the heart of what web 2.0, enterprise 2.0 and km 2.0 are all about! Its a different mind set that many people still do not get or like to see
Open source thinking is sharing and remixing. You've got to set your ideas free, you can't control your content. It is a different mindset: "Ah darn, someone else has got there first" versus "Great, don't have to do that, I can build it on it!" For me, it's been the ability to think out loud with colleagues on ideas and topics, share presentations, etc.
