Hello students!

This is my first post. The most interesting thing I’ve learned today was from Clay Shirky who told me (via youtube, although my goal is to talk to him in person sometime) the following:

About 100 million hours of thought were required to create Wikipedia.

About 200 billion hours are spent in the U.S. watching television every year. That’s 2,000 Wikipedia projects.

World-wide Internet-connected people spend one trillion hours watching television ever year. that’s 10,000 Wikipedia projects every year.

That’s what Shirky calls “Cognitive Surplus.”
