In 1985, a precursor to the Internet was devised by two men in San Francisco.
Their invention was the Well, an electronic network intended to be a "virtual community" analogous to the communes founded in the hills of Northern California, Colorado and New Mexico. The Well let members discuss such topics as technology and the Grateful Dead via a form of instant messaging.
It is easy to spot what the Well of 1985 became: the current Web 2.0. The virtual community has been replicated in social networks such as MySpace and user-generated content such as YouTube.
