Hitting a nerve with Web 2.0

In an article by Andrew Keen, he rants somewhat about Web 2.0 being a bit too reflective on ourselves. I find myself agreeing somewhat with the problem of reflection. Being that this is my blog, of course the whole thing is reflexive from the get-go, but bear with me. The web is a dangerously filtering medium. Web 2.0 makes it even more so. Communities of likeminded individuals keeping to their own interests. I’m tempted to make a roulette style take me somewhere new website that is as random as possible. Of course any mechanism I would consider using (search engine based) would of course not be completely random.
I’m getting annoyed with the virtual community building. we need to build real communities.
