I think you forget that each computer requires an operator. So in essence the internet IS a network of biological organisms.
I think of it more like a really large society, but with less laws, and fewer ways of really enforcing the laws that exist.
Hence, you get sites like 4chan and a tonne of porn sites. The upside is that you still get sites like talkbass.
I'm actually kind of glad a site like 4chan still exists. Because it makes the internet seem more "wild west" like.
I still prefer Talkbass, though. Nice avatar, btw.
