So Mark Zuckerberg walks into a bar — sorry, no punch line. According to a "missed connections" posting on Craigslist, Facebook's CEO visited Bourbon & Branch, the Tenderloin speakeasy, on Saturday, and rolled his eyes when he was recognized. The Craigslist user's unfriendly advice for Zuckerberg: "If I were you, I'd appreciate being recognized. You're not Brad Pitt. You're a computer geek (on paper). Don't become such a prick so early in your career." We have a feeling this will cause the straitlaced Zuckerberg to drink even less than he already does.
