Crowdsourced document analysis and MP expenses

My former Yahoo! colleague Simon Willison is doing some amazing work setting up near-instant crowdsourced content analysis systems for government documents in the UK. He and his team are developing vital knowledge about what works and what doesn’t in these kinds of systems, and he’s shared it on his blog:

News-based crowdsourcing projects of this nature are both challenging and an enormous amount of fun. For the best chances of success, be sure to ask the right question, ensure user contributions are rewarded, expose as much data as possible and make the “next thing to review” behaviour as solid possible. I’m looking forward to the next opportunity to apply these lessons, although at this point I really hope it involves something other than MPs’ expenses.

Who is doing this kind of thing in the US, I wonder?
