The Internet is a Ponzi scheme of human knowledge

Quote from Sketchbook by Ivan Brunetti: "Sometimes I think the entire Internet is an elaborate Ponzi scheme of human knowledge." (from p. 107 December 21, 28 New Yorker from 2009). This quote seemed like a good counterpoint to today's PLENK2010 Elluminate session with Harold Jarche. Some points: Drink from the firehose. (I guess the question is how much of what we drink from the firehose is junk? What filters do we need in place?). Leave some time for reflection. Use a blog for reflection and (based on comments from some participants) don't censor yourself too much. Put your ideas out there and be willing to accept critiques. Downes noted that sometimes he goes back and puts an "update" at the end of an old blog post if he's changed his mind about something. Another thread from the Elluminate: How can we change the established concept of and what happens at a "university"?
