You Need To Win A Lottery To Attend Google I/O
 

If you plan on attending Google I/O in June, you better be prepared to win a lottery. This year's conference will be held from June 25-26, and will be taking place once again at the Moscone Center in San Francisco. The timing was announced by Google senior vice president Sundar Pichai on Google+, though Pichai didn't share any details on what to expect.
