Shy Breaker wants to help you overcome your normal reticence and meet other people through the Shy Breaker desktop and iPhone application.
Using Shy Breaker users can drop a note on a Google Map. The note can be about someone you've spotted and would like to meet or it could just be a note to say you would like to meet other like minded individuals. Users can time-stamp their notes so that they only appear on the map for a specified period of time.
If other people want to respond to your note they can reply to it and start a private conversation using the application's messaging system. I guess the rest is then up to you ...
