Cool beans! It is sort of scary how the Lab knows every move we make, but of course they do, so probably better we not forget the fact.

I'm amused that they used gestures in particular in their study; I wonder if they know the extent to which that selects a subset of SL users. I hardly use gestures at all, myself, and can't remember the last time I gave one to someone, and when people give them to me I say thanks and then lose them in inventory forever.

Would be interesting to compare gesture-giving patterns with those for, say, animations, notecards, prim-objects...
