This looks like an interesting community. Going since 1985 it seems to be a classic example of social networking at work. Who said this was new?
Have spent some of the evening browsing TED talks
Wow there are some amazing speakers here. Became fascinated with listening to Larry Brilliant talking about the eradication of smallpox. He also discussed Sars and Birdflu and the fact that the only way to combat these diseases is early detection early response. He also described GPHIN
an organisation based in Canada that uses the power of the net and networking to detect diseases way before it was possible by other means. His is a fascinating speech and certainly makes you think about the power of collaboration.
