I've never been to Burning Man myself, but I'm aware of the event due to Drizzle development stalling to a halt during that festival. In other words, I have many friends that go there.

It was interesting to read a statement from the organizers of Burning Man about the fact that this year there is way more demand for Burning Man tickets than they can sell. Apparently even the desert has its limits (and more so the road leading to it).

Organically growing volunteer projects are exciting because they just grow and grow and there seems to be nothing there to stop them. But once in a while they hit bottlenecks that need to be solved.
