Google Moderator

Google Moderator

http://moderator.appspot.com/

Last year, Google engineer Taliver Heath used his "20% time" to create a tool that lets event organizers solicit questions and debate topics from the public. In December, Google Moderator went prime time as then-U.S. President-elect Barack Obama used the site to hold a public forum called "Open for Questions." Google doesn't charge for or run ads on Moderator, but does use the service to get feedback from users in topics such as "Ask a Google engineer" and "Suggest an Android application."
