Completely irrelevant to this post. A long time ago I was in an Android "workshop" in one of these Google conferences and I saw a tall guy with a cowboy hat and slippers walking around and talking to people. I though to myself, "what a funny guy". We chatted for a little while and I didn't know if he was a "Google evangelist" (those that can talk tech but can barely code) or if he was just serving coffee (he was super humble and relaxed). Then I learned that was Tim Bray, one of the "creators" of XML. I never underestimated anyone anymore (I was young and stupid, sorry).
