When techies get mad, as they did when Sarah Lacy interviewed Mark Zuckerberg at SXSW, they Twitter furiously. When they're still seething later, it seems, they put those Twitters in a spreadsheet and analyze them. Hence, Somewhere Inc. CEO Kee Hinckley's Anatomy of a Mob, which charts the frequency of the top 50 words Twittered over the hour Lacy and Zuckerberg spoke. Hinckley's conclusion: "The Twitter transcript makes it clear that there was an early and constant stream of negative comments flowing from a large number of senders." Lacy has cited live blog coverage as evidence that the mood stayed positive until the last 15 minutes of the interview; Hinckley's analysis — though relying on Twitter — would seem to argue against that. Even so, Hinckley is sympathetic: "She didn't deserve the abuse that was dished out on Twitter, let alone what happened in the auditorium." After the jump, an annotated video showing the Twitter reaction in sync with the interview.
