Large Speech Corpora - Dan Bricklin's Insights

Just when I thought I'd finished with this topic (point 3 in my presentation on Monday, revisited in yesterday's post), I see an interesting post on O'Reilly's Radar this morning, summarizing a paper from Dan Bricklin in 2001, The Cornucopia of the Commons.  Here's the summary from O'Reilly:

The insight, which Dan outlined in his paper, The Cornucopia of the Commons, is as follows: There are three ways to create a collective work: 1. Pay people. 2. Get volunteers. 3. Architect your product in such a way that people create collective value by pursuing their individual self-interest. By way of example, Yahoo! built their directory using method 1. Many open source projects as well as shared content projects like Wikipedia use method 2. But many of the great successes of the Internet age have discovered method 3.

What I've been proposing as the way to accumulate large speech corpora is to pursue Dan Bricklin's method 3, i.e. provide ways for people to contribute while pursuing their individual self-interest.
