"MD #1: It's Expectations Management 101 Week," @GSElevator tweeted this morning. What's so great about @GSElevator? The handle claims to tweet overheard conversations from actual Goldman Sachs employees (MD stands for managing director). And the feed, which has more than 127,000 followers, was one to watch after the investment bank released its fourth quarter earnings today. So all of its tweets today must be about the 48% drop in profits, right? Well, not really. Here's @GSElevator's last tweet: "#1: Lately, I don't even call it a hangover anymore. Its just the morning."
