Google Moderator, which launched on September 24, 2008, a simple tool that helps groups resolve which questions should be asked at all hands meetings, conferences, Q&A sessions, etc. The idea is that there are always lots of good questions to ask in a limited period of time, but it’s hard to recognize which questions the attendees are most attracted in hearing discussed. Moderator lets users add questions and vote on the questions of others, so the emulsion rises to the top.
"I premeditated a tool in my 20% time that would permit anyone attending a tech talk to propose a question, and then confer other participants a way to make your choice on whether or not that inquiry should be asked. This way, the most popular and pertinent questions would rise to the top so that the presenter or the moderator of an occasion could run the conversation more efficiently and in apparent manner. The tool, which we internally called "Dory" after our favorite question-asking fish in Finding Nemo, quickly grew to other parts of Google including our weekly all-hands company meeting, as well as for our series of talks led by political candidates or distinguished authors."
