Instead of trying to use the Internet to solve a problem that is better solved in real-life (i.e. meet people and talk), why not create a whole fiction world where you can be anything you want. Basically, it's a game where you put the profile picture you'd like to have, and the 'about me' you'd like to be. So, you talk with lots of strangers and avoid the awkard thingy while still having fun and meeting people. Of course, after some time, it will naturally start to be more intimate and it'd be possible to share more real stuff.. but that's not even necessary.
Think about all the guys and girls in couple who'd like to have fun dating again but can't because they're already in relationship? Or single players who just want to have fun?
Here it is. It's rough around the edges but I hope it inspire someone.
