That thing is pretty good, but has too much of the authors (often bad) attitude strung through it.
When people ask about different kinds of EDM's out there, I typically point them to beatport.com and tell them to just go look at the different pages available on the 'Genres' drop-down. It's an excellent way to quickly understand the difference between the bazillion varieties of EDM (it breaks it down into 16 or so genres, which still means a bunch aren't listed or are munged together.)

What really caught my attention was that dude holding that laser and moving it to the beat... If that beam were to hit your eye you'd be blinded, and not just flash blinded, possibly some serious damage, especially given the lighting conditions. Notice how the beam flashes the camera: it's hitting objects at eye-level. Some day a major blinding incident is going to occur, maybe not at Burning Man, but somewhere, and the FDA is going to clamp down on them like Australia and Sweden. It's going to suck, and I'm going to be pissed.

For these kinds of shows, the lasers as set up by professional laser show operators. In order to ensure that there are no liability problems, these laser show operators ensure that their lasers are either 1) completely out of reach (3m above peoples heads is usually the standard), or 2) the maximum permissible exposure (MPE) measured for all locations that the laser directly interacts with people falls below Class 1 laser standards (i.e. usually 0.5-1mW or less).
The latter takes quite a bit time and measurement. For lasers that are not eye-safe at aperture (the opening), they can be made safe if they move fast enough, or spread out enough to not be an eye hazard. However, the operator needs to ensure that the laser cannot get stuck in a position due to mechanical problems, or that if there are mechanical problems, the lasers will shut off.
The work and liability of ensuring that laser shows work right is one reason why audience scanning is not as popular in the US as in Europe. Usually only large venues will have the resources to ensure that MPE levels are maintained for audience scanning. Supposedly, the people at the Laser Genome project this year were fully compliant with their laser safety measures, including FAA variances. The group that did One-Mile-Clock in 2011 may not have been up to those standards, but they did take measures to ensure that the beam intensity at points it intersected on the playa (e.g. the temple) were low power enough that reflections from stuff, like the crystals, would not blind people (they also ensured that beams would terminate on hills).
In many ways I like that Burning Man is "lawless" with respect to lasers, at least on art and safely installed. It means we get to see lasers used in ways that usually can't be seen because of liability issues. However, I get really wary of handheld lasers or stuff like that where people just aren't aware that they could blind someone with their toy.
