For the roundup of the week, Craig and Sean discuss the happenings at Tech Stars Demo day NYC. This includes superstars like Condition One (an app that gives you full immersion into a video) and Pickie (a social news aggregate like Flipboard). The big news of the day involves Yammer being acquired by Microsoft for over $1B helping pave the wave for even more social media acquisitions. Are they playing catch-up or does Microsoft have bigger plans for the B2B space?
