A computer that helps people to get over their shyness and make new friends
By tracking where the different users go (eg. events, talk they attend, bars, concerts, etc) and matching it with other users, people can get suggestions of other participants that have common interests, thus go to the same events. Additionally, bringing some A further funky step would be for the system to randomly give meetings to these users by sms at randomly chosen time and locations somewhere where they are both present (eg. "john and anna, you guys should definitely meet at the entrance of room 44 at 5pm, you got lots of things in common to discuss"). Eventually, such a computer generated rendez-vous will bridge people who were meant to do business together. Or marry.
