clickworkers In the middle of reading a long paper on the economics of open source development (which I'll write about once I'm done), I discovered a very interesting NASA project:

A pilot study conducted on the Web site between November 2000 and September 2001 attracted more than 80,000 people who marked nearly 2 million craters for measurement and classified the relative age of another 300,000. Their averaged results proved to be just as good as those produced by an expert crater rater—who would have had to dedicate several months of continuous effort to produce the same amount of data.

Will we someday see tedious scientific research farmed out to third-world "sweatshops"?
