It's time for a confession: I have never been to an open source conference. I've been an open source and free culture advocate for more than half a decade. I've used open source operating systems and applications on my computers and mobile devices for nearly as long. I've contributed to open source documentation efforts. I've organized a university event to promote the principles of open source in college. And I've been writing for opensource.com. But I've never been to an honest-to-goodness, full-blown conference.
