It's a neat way to get people to think about it (although I agree with @tantek that it's meaningless without a dialogue about surveillance). Looks like a neat conference; wish I'd been there.

It's an interesting method of stating a preference, but it's a public event. No reasonable expectation on privacy.

For the record, there are very few attendees wearing red, and only slightly more with yellow. The vast majority chose blue. When @caseorganic took a photo of her audience for the live demo, she had to ask one person, and point the camera away from one person. Everyone else in the room had blue.

Good example of surveillance theater. Let's shame the *occasional snapshot* taking individuals as a way of distracting everyone's attention from the ubiquitous *continuous recording* faceless anonymous "hidden" camera operators (all this black brown silver globes in the ceiling of nearly every store and office/gov/common area building.

What on Earth sort of conference is that? The only ones I've been too where there was a problem like that had undercover security services with badges indicating which service they worked for...?
