This guy aside, it's easy to imagine the many ways Google Glass could come in handy on the pickup scene: "Okay, Glass, look up her Facebook profile and tell me which bands she likes." "Okay, Glass, now tell her how compatible Geminis and Cancers are." "Okay, Glass, now find a dark alley nearby where we can make out awkwardly." Or, if things aren't going that well: "Okay, Glass, take a photo of her cleavage before she runs away."
Unfortunately for our SXSW Googler and other early adopters, "Okay, Glass, now make these glasses look cooler than a Bluetooth earpiece" is not yet a recognizable command.
