Thanks to Internet, it is possible for a musician in Bolivia to be listened to in Toronto. My blog is read by people in Brezil. However, there is a very serious threat on this brave new world: that individuals and small communities get lost in the ever increasing noise. Just think about how progressively less reliable and useful email has become. I think this is partly a technology issue: we need increasingly poweful tools as cyberspace grows.
It just seems that simple HTML cannot cut it anymore. We are increasingly relying on the web as a publication tool and need to make it more flexbible for our needs. New tools are being built (MathML, LawML) to put on top of it, but adoption is slow.
