The fractured individual identity that comes with multiple social networks used to be easy. You were who you were depending on who you were with. Now with the persistent nature of Social networks it is nearly impossible to maintain your own identity consistently, seeing that you have so many different user groups converging in one open arena. I think this was an unintended consequence of open social networking spaces. I love this video - it captures the realities of juggling not only multiple identities but multiple identities on multiple spaces.
