Over at iconoculture, they have an article about Thinknets

They say, that

Traditional think tanks are evolving into “thinknets� (a.k.a. transnational thinknets) where great minds collaborate across the globe.

Now they do realize, that the idea is not new, and apparently the US Navy explored things like that in the late 90s.
It’s interesting stuff, considering how the net changes the way people work on things across the globe.
Isn’t the whole wiki movement and, in a way, the blogosphere already doing that? Admittingly, the blogosphere is a rather chaotic grouping of thoughts and ideas, but you can see how certain themes run across several blogs, for example at blogdex.
