Rheingold on blogging:
Blogging grows collective intelligence.

Every blog is, in a sense, a group map of a particular segment of human experience.

Consider the size of the “blogosphere”: expected exceed 10 million by the end of 2004. (This is 2002’s writing. the real number you already had in the class. What was it again? )

While individual blogs may come and go, blogging is likely to become a staple format for online publishing, providing an ever evolving map of human knowledge – from bottom up.
