Facebook's IPO Roadshow Off to a Frustrating Start Things got off to a late start because Zuckerberg was ... in the bathroom?

(AP Photo/Paul Sakuma) (Newser) – Facebook kicked off its IPO roadshow yesterday, and while some elements of day one were perfectly predictable—Mark Zuckerberg showed up in a hoodie and sneakers—others were a little more frustrating. Things began an hour behind schedule, Zuckerberg showed up late to the Q&A (CNBC's explanation: He was in the bathroom), the presentation featured a video that many potential investors had previously viewed online, and the audience was only given enough time to ask eight questions, reports the Washington Post. (Reuters reports it was actually just five.) One of them was about Facebook's purchase of Instagram, which Zuckerberg defended and said he would do again, noting that Instagram's user data passed a "tipping point" that signaled it would grow much larger. One other detail of note: Security was apparently pretty extreme. Would-be investors had to show several forms of ID and be cross-checked against a list of attendees.
