How Do You Use Your Cognitive Surplus?

What do you do with your free time?
Do you spend it creating, or do you spend it passively consuming?
Typically, we all do a mixture of both (we are human, afterall), but in this TED video from Clay Shirky, he explains how the 1 Trillion hours of free time can impact our society in the most positive way.
One point that struck me is how new media is giving us a chance to *create* instead of just watching tv (he seems to point at TV as the root of all evil, haha), especially when he points out that Wikipedia was built out of roughly 1 percent of the man-hours that Americans spend watching TV every year.
Shirky gives two examples of how cognitive surplus has been used to "create" something of value - first off, LOLCats. Second -, which has allowed Kenyans to sidestep government censorship and report on acts of violence in real time and has since been deployed worldwide in a variety of useful ways (after becoming open source).
In his book Cognitive Surplus, Shirky forecasts the thrilling changes we will all enjoy as new digital technology puts our untapped resources of talent and goodwill to use at last.
So readers of the Techyness, how do you use your cognitive surplus?
