art, or bit of information.  Memes use human brains as "survival machines"
and they hop from brain to brain and across time and space
("communications") in the process of cultural (as distinct from biological)
evolution.  The Internet is a latter day meme-hopping playground.  But, more
importantly, it is a Network.  Genes move from one container to another
through a linear, serial, tedious process which involves prolonged periods
of one on one gene shuffling ("sex") and gestation.  Memes use networks. 
Their propagation is, therefore, parallel, fast, and all-pervasive.  The
Internet is a manifestation of the growing predominance of memes over
genes.  And the Semantic Web may be to the Internet what Artificial
Intelligence is to classic computing.  We may be on the threshold of a self-
aware Web.
