As a young adult I was neck-deep in free software ideology for years, utterly convinced and pitching it to people who truly didn't care. I could draw more than a couple of parallels with religion. I snapped out of it in my mid-20s, and I came away with a respect for the basic ideas and way too much of the discourse bouncing around in my head. Annoyingly it's now one of my main cultural touchstones that I've never fully displaced, so I can't help writing about it all the time.
