Who do I have to "tweet" to get a free drink around here?Putting the "social" in "social media" are Tacit Knowledge VP Oz Sultan, left and Yerba Buena Center Webmaster James Im, right — with both mauling online marketeer and TechSet party cohost Stephanie Agresta, center. They were probably trying to kiss their way to free drinks, since the cash bar was charging $9 for beers and $13 for mixed drinks. But hey, there were free fried cheese sticks! Can you come up with a more compelling caption? Kiss one up in the comments and we may just kiss you back by making it the new headline.
