This video by Michael Wesch (Kansas State University) illustrates the flowing, intertextual and massively communal nature of our growing internet:
When we post and tag an image, we are teaching the Machine. Each time we forge a link, we teach it an idea. Think of the 100 billion times per day humans click on a web page what we think is important teaching the Machine.Web 2.0 is linking people…
… people sharing, trading, and collaborating…
We’ll need to rethink a few things… copyright… authorship… identity…
It’s both a beautiful celebration and a little disturbing. Maybe I’ve watched too much Matrix. 
When I checked out the YouTube page, there were 3113 comments (love the symmetry), here is a small selection:
ferment666: The more connected we become to virtual reality, the less connected we become to actual reality.
grantium: If we’re teaching the machine, who’s teaching us?
