The most eagerly awaited session of the day was the Mark Zuckerberg session. He is the CEO of Facebook, and that is no small task. The queues outside the Palais had to be seen. Even the Grand audi, where the session was being simultaneously telecast, was packed. However, the session by itself was boring. He was too guarded, gave the usual answers, which revealed nothing. For a company that has 500 million users, surely the CEO should have been more upfront, writes Rahul Kishore.
