Why the HTE can work now

I'm just going to provide a link to an interesting article about social projects on the internet, because there's no sense in my summarizing it when these quotes do the job:

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. Or put still another way, in the U.S., we spend 100 million hours every weekend, just watching the ads. This is a pretty big surplus. People asking, "Where do they find the time?" when they're looking at things like Wikipedia don't understand how tiny that entire project is, as a carve-out of this asset that's finally being dragged into what Tim calls an architecture of participation.
[...]
Just to pick one example, one I'm in love with, but it's tiny. A couple of weeks one of my students at ITP forwarded me a a project started by a professor in Brazil, in Fortaleza, named Vasco Furtado. It's a Wiki Map for crime in Brazil. If there's an assault, if there's a burglary, if there's a mugging, a robbery, a rape, a murder, you can go and put a push-pin on a Google Map, and you can characterize the assault, and you start to see a map of where these crimes are occurring.

Maybe this will succeed or maybe it will fail. The normal case of social software is still failure; most of these experiments don't pan out. But the ones that do are quite incredible, and I hope that this one succeeds, obviously. But even if it doesn't, it's illustrated the point already, which is that someone working alone, with really cheap tools, has a reasonable hope of carving out enough of the cognitive surplus, enough of the desire to participate, enough of the collective goodwill of the citizens, to create a resource you couldn't have imagined existing even five years ago.

With the right tools on the internet, we can use some of those free-time television hours to come up with some really solid thoughts. Now we just need to get those tools in order and maybe we'll be one of the experiments that works...

The whole article is definitely worth reading:
