A Wiki’s-worth of Human Activity
This is an eye-opening visualization of “cognitive surplus” from www.informationisbeautiful.net:
Thus, in the amount of time U.S. adults spend watching TV in one year, roughly 2000 Wikipedia-style projects could be created.
I once heard someone suggest a wikipedia as a unit of measure of collective human cognitive output. So every year, U.S. adults spend 2000 wikipedias watching TV. How can we more efficiently harness this cognitive surplus?
