really? though I don't think I'd ever participate in one of these, I can see the appeal...i could imagine it being a pretty cool experience even if it just to see people react to a roving mob of people taking pictures. I don't see how it's that different from any photographer doing a photoshoot? is it just that are so many shooting the same subject at the same time? photography is so many different things, capturing a moment, documenting action, making an image, as well as all the different variables of lens, proximity to subject, focus, angle, light and perspective; not to mention editing in post...that 10 people who are shooting the same thing will likely make very different decisions about their shots. and that, to me anyways, is pretty interesting; granted it isn't for everybody but I don't see why it would be stupid or any more stupid than any other type of photography...
