Google Answers was an Internet search and research service offered for a fee by Google, “answer brokering”. It was launched by Google in April 2002, and went out of Beta in May 2003. In late November 2006, Google reported that it planned to permanently shut down the service. As of November 30, 2006, new questions may no longer be asked, but existing questions may continue to be answered until December 30, 2006.
Worth a look at the video. It is a great example of effective multimedia for the web, like your union organizing. Here is a link to the Save Google Answers Blog. If you are in a union and have a cause you would like to promote, an issue to advocate for, or something you would like to save, this could be a great approach! This could be effectively used for organizing if done well.
