Howard Rheingold talks about exploring cooperation
I recommend viewing this talk (you can do it directly if you have flash, or install miro and add a TED channel to it which is a better option ). It talks about things like Prisoners Dilemma and how people are increasingly escaping it by cooperating, by turning distrust into assurance.
What impresses me the most, however, is the notion that we've just begun exploring cooperation and "technologies of cooperation". I like this notion because I occasionally feel like it's already done, blogs are everywhere, there is a saturation of forums, everyone can have a web site or a social network etc. - how can we do anything new here?
But the realization that we're just beginning and that cooperation is an universe still waiting to be explored makes for a motivating challenge. I am happy that we have this beautiful think tank developing on Libervis.com where exactly this kind of topic fits so well - and we will be exploring it!
