High Quality Content by WIKIPEDIA articles! Google Moderator is a Google service that uses crowdsourcing to rank user-submitted questions, suggestions and ideas. It was launched on September 25, 2008. The service allows the management of feedback from a large number of people, who can vote for the top questions that they think should be posed and ask their own. The service aims to ensure that every question is considered, lets the audience see others` questions, and helps the moderator of a team or event address the questions that the audience most cares about.
