The UK group mySociety has produced an astonishingly steady stream of political innovations. The latest is a crowd-sourcing add-on to TheyWorkForYou.com, which provides comprehensive information on your local MP.

TheyWorkForYou now has video of speeches in Parliament, taken from the BBC. They also have the complete text of Parliamentary debates from Hansard. So the site is asking readers to match the two. A Flash-based application lets users match the written speech to the video. Results are stored and time-stamped. At a quick glance, it looks like an extension of the kind of technology that powers the wonderful dotSub.
