• The idea is to help introverts and other shy people to befriend strangers in public places without the feeling of "being a creep" that nowadays people have when they want to say Hi to strangers.
• User creates a profile with a few personal pictures, nickname, self description, interests. What topics you like to talk about, political affiliations, etc. Anything to help start a conversation.
• App can use Bluetooth to detect other users nearby and communicate. Bluetooth(or local place) profile broadcast is optional though.
• App uses GPS to list people from the same town or from another form of local area, like being less than 5 Km or 10 Km from user. "Town broadcast" is also optional. Precise distance should be hidden if less than a Km.
• Users who are not broadcasting their profiles can still se those who are and send messages to them.

This is just the sketch of an Idea I was thinking about this morning. Feel free to comment below.
