Facebook kicked off its IPO roadshow in New York City on Monday, with CEO Mark Zuckerberg sporting his trademark hoodie sweatshirt and sneakers. A 30-minute video was part of the presentation, along with a Q&A session in which Zuckerberg and other executives took questions. The format apparently did not suit some attendees, so Facebook made some tweaks. When the show reached Boston on Tuesday, the video was gone.
