Steve Rubel’s new taxonomy for social media:
* Galaxies: centers of gravity that attract the like-minded – e.g. YouTube, Digg and Second Life
* Stars: online celebs, such as Robert Scoble, Thomas Hawk, AskaNiinja, etc.
* Planets: individuals who follow the stars, yet are influential in their own right
* Shooting Stars: insta-celebs that create viral videos or memes and then fade
* Comets: recurring themes, such as transparency, veracity and entitlement
* Asteroids: desolate, lifeless places with negative energy — think splogs
