I learned a long time ago that the only way to earn your @Klout is to walk up to the biggest dude on the block and stab his brain with his nose bone.

But I couldn't track down @Klout kings like @KanyeWest and @BarackObama, so instead I went to hang with @Gregarious, who helps run the San Francisco-based @Klout (which he describes as “CarFax for people”), and who was at MIT buying rounds for Twitter geeks last night.
