How well do you know your social network?

I was very intrigued by this social media game a friend of a friend has created as a way to learn more about your social network. The name of the game is Placetheface. After allowing access to your facebook, linkedin or meetup network, a picture comes up of a friend in your network and you must try to identify the person. When you enter the right name, basic information about the individual is shared to help you learn a little bit about who the person is and what they do. The information is extracted from the individuals facebook, linkedin or meetup. Placetheface engages you in two ways. It is competitive; at least to me. You want to guess the person's name right. Of course you will be able to identify your good friends easily, but some faces can be extremely unfamiliar. Secondly, Placetheface acts as a social network educational tool helping you to better recognize faces. I think we have all been in that awkward situation where we see a person we are friends with on facebook, but either we haven't see the person since highschool or we have hardly talked to them more than once, and remembering their name becomes as challenging as remembering what we ate for breakfast on July 3rd 2002 (completely random date). What do you do? I'll tell you what I do, make awkward eye contact until their is or isn't an agreed upon mutual recognition of each other. If social engagement is made, I use neutral greetings such as "Sup dude?" or "Hey girl" or even just a head nod and keep walking. Placetheface may just save us from these awkward scenarios. Even if it doesn't, its a great way to kill some free time when your bored...
