For shy people, making the first move towards starting a relationship can be hell.
I suggest the following. People entering a bar or club can send a text message to the number displayed inside. This would consist of their personal profile: yes/no responses to up to a few hundred questions they have previously completed online. The SMS server would find the best match to their character and stated requirements amongst those people presently within the bar.
A previously stored image of the newly arrived person would be sent to the matched person’s phone, who would have the option to say yes to a meeting. If the response is yes, then the matched person’s image would be supplied to the newcomer, giving them say 15 minutes to meet and introduce themselves. If a no were received, the next best match would automatically be sought.
On exit from the bar, each person would be reminded to text a goodbye message, removing their profile from the pool.
This use of technology would perhaps help to remove the over-reliance on appearance which rules out (or dooms) many relationships.
