The Internet has been evolving technically, and metaphorically, for many decades. In the pre-Web era the Internet was thought of mainly as a computer network -- a communications system not unlike the telephone network, but for machines (and in some cases people) to talk to each other.
In the 1990's with the advent of HTTP and HTML, the metaphor of "the Web" was born and concepts of webs and sites captured our imaginations.
More recently, in the first decade of the 2000's our focus shifted to social networks, and the emerging social graph -- the notion of graphs that involve more kinds of nodes and links also emerged, leading to speculation about the potential of a more semantic Web.
Now, as we move into the second decade of the 21st century, the next big new metaphor may be the Stream.
