To recap this very short public service announcement: a very limited number of people, selected by Google and willing to drop $1,500 and maybe the cost of a flight and hotel, are going to be wearing very obvious headsets, which they have to address verbally ("Okay Glass ...") or pointedly tap to activate. They will mostly be using them to take pictures and videos, get directions, and ask goofy questions when nobody is listening. There is no advertising, no inherent revealing of locations, and they will basically invade your privacy only slightly more than they already do with their smartphones.
Stay calm, and wait until everyone else figures out the bugs, awkwardness, and battery life. You'll know Glass is around when you see it.
