This video will mainly interest scientists who are interested in social media and its use in networking (blogging, Facebook, Twitter, etc). Scientist took a while to accept this new media, and many are still suspicious or reluctant to use it. But at least the media is being discussed and considered these days.
This is a Google Hangout video of a discussion by 5 US scientists. it brought home to me that different people use these media for different purposes and in different ways. As a retired scientist my use could be very different to the way a working scientist uses it. And scientists involve in policy issues, or science communication, will use it differently to those involved in teaching and/or research.
