It started with a car ride in Munich on Monday night. I was leaving a big party put on by DLD, a social-media conference, and was planning to walk back to my hotel. But then another party-departer tapped on the window of one of the DLD-labeled sedans parked outside the Haus der Kunst, and asked if he could have a ride back to the hotel. The driver said yes, it was the same hotel as mine, so I jumped in too.
