Plug into facebook. This will allow you to attract users because there's no registration barrier, and collect information about the user's tastes and interests. Then use that information to find like-minded individuals who would be a good match. Now you could connect that with your GPS idea. If you're within, say, five miles of a good match, a notification goes off on your cell phone saying you should meet this person. If both parties confirm, your service would provide a means of having them connect in real life. Either it could call them both and connect them, or it could propose a mutual location for them to meet.
