I don’t repost from Boing Boing, assuming most of you follow it, but this entry is straight from my heart. Clay Shirky should be invited to TED if you ask me.

For the first time, society forced onto an enormous number of its citizens the requirement to manage something they had never had to manage before–free time.

And what did we do with that free time? Well, mostly we spent it watching TV.

We did that for decades. We watched I Love Lucy. We watched Gilligan’s Island. We watch Malcolm in the Middle. We watch Desperate Housewives. Desperate Housewives essentially functioned as a kind of cognitive heat sink, dissipating thinking that might otherwise have built up and caused society to overheat.

(…) So I tell her all this stuff [about WIkipedia]. She heard this story and she shook her head and said, “Where do people find the time?” That was her question. And I just kind of snapped. And I said, “No one who works in TV gets to ask that question. You know where the time comes from. It comes from the cognitive surplus you’ve been masking for 50 years.”

So how big is that surplus? So if you take Wikipedia as a kind of unit, all of Wikipedia, the whole project–every page, every edit, every talk page, every line of code, in every language that Wikipedia exists in–that represents something like the cumulation of 100 million hours of human thought. I worked this out with Martin Wattenberg at IBM; it’s a back-of-the-envelope calculation, but it’s the right order of magnitude, about 100 million hours of thought.

And television watching? Two hundred billion hours, in the U.S. alone, every year. Put another way, now that we have a unit, that’s 2,000 Wikipedia projects a year spent watching television.

(…) I could sort of see what she was thinking: “Losers. Grown men sitting in their basement pretending to be elves.” At least they’re doing something. (…) However lousy it is to sit in your basement and pretend to be an elf, I can tell you from personal experience it’s worse to sit in your basement and try to figure if Ginger or Mary Ann is cuter.

Disclaimer: I almost completely quit watching TV a couple of years ago. My weekly average is under one hour. The one single reason is it’s brain-mushing stupidity drives me bonkers. Try it for a week. Set some goals, like 8PM news only. You might not regret it.
