I saw a young friend of mine on Facebook posted some "It Girl" illustrations so I clicked over to see what all the fuss was about. I was intrigued/alarmed, because my first thought was that the "It Girl" images looked pretty much like Barbie if Barbie was a trendy teenager and she went to raves and/or appeared on a reality show and/or was a young hooker and/or had multi-cultural, fashion-obsessed friends.
There are 9 million "It Girl" users on Facebook. It is an avatar-based online shopping game. And here, verbatim, are the rules.
