getting a second life

Had an interesting chat with Joanna Wombat on Second Nature
(after Joanna helped me to actually get there)

I don't entirely understand Second Life, but it does seem like a useful environment for 3D stuff.

Right now I'm just kind of thinking about science and visualization.  What would be a useful presence?  A gateway related to specific journals?  To all STM information?  To Canadian S&T?  How much of one's organizational presence in the real world should one try to carry over into SL?
