http://www.youtube.com/watch?v=JtRJXnXgE-A&hd=1 As part of our continued effort to be more transparent about how search works, we're publishing video footage from our internal weekly search meeting: "Quality Launch Review." We hold the meeting almost every Thursday to discuss possible algorithmic improvements and make decisions about what to launch. This video is from the meeting that happened on December 1st, 2011, and includes the entire uncut discussion of a real algorithmic improvement to our spell correction system. The language can be technical, so we've included annotations to provide some context for the discussion (and have a little fun!).
