Nature network

I still don't know if the idea of science 2.0 is inside or outside of my research focus. Anyway, there is something moving on. I just found a network related to Nature where one of the more active groups is named "Scientific researchers and Web 2.0: Social not working".
If a domain-specific portal can be an information hub for academics, there must be some links between this and science 2.0.
