I met him at a meetup I went to out in SF while traveling for work. I didn't know anyone there, just going to kill time. I had no idea who he was just someone willing to chat with me for an hour or so. I started asking him what he did, and it was clear he wasn't there to talk about himself. Just struck me as a really cool, really humble, really approachable guy. With a lot of good ideas, and a passion for spreading curiosity. World needs more people like this, not less.
