Gettin' it onnnn.. bluetooth style
Nokia have this cute little app called 'sensor'. The basic premise is that people set up a local profile on their phone, and the sensor app picks up other sensor users around them showing their profiles. Obviously, shagging ensues. I mean conversations!
What would be interesting with this is to see how/when they blend larger communities with this, so the local expands. For example a mySpace'd up version would be interesting.
