You’re invited — How many newsletters do you get that feed not only your mind but your  stomach? After skipping a year our N-Square Dinner is on for May 15th. Doors open at 6PM for schmoozing and dinner is at 7. The topic for the evening is Social Business & Big Data.   Both of these topics are hot: How does a company integrate with and leverage all the modern forms of social networking? What’s realistic, what’s aspiration and what’s insanity? In our normal style we’re going to get a few key partic­ipants and stage an enter­taining and infor­mative debate. RSVP — John Katsaros
