Once it gets into the hands of the pubescents out there, any social norms may be thrown out the window. Today's kids grew up w/ the likes of FB/twitter/etc, and saw no problems with sharing everything about their lives on the 'net. Today, many or most do not care that they are constantly broadcasting their location to the ether, with GPS accuracy (I might add, as most of us put up with the fact that we broadcast our locations to cell towers at all times). Tomorrow's kids, once price and availability for Glass (or something like it) are more consumer oriented, will glom onto it as a favorite new toy. There will be lots of apps and utilities; new social sites designed for Glass such as FacePalm (tm) that the kids will flock to (until their parents learn how to use it); and they will create their own games and memes.
Hey you kids, quit looking at my lawn!
