Back in 2008, Google launched Google Moderator , a tool to help presenters prioritize questions for Q&A sessions. Since then, we've seen it in action a number of times, often from the company itself, but also in political settings, and other democratic-style events. "Google Moderator is used extensively within Google for meetings and to collect feedback from Googlers on events or happenings within the company," says Colby Ranger of the Google Moderator team.
