Improving MSN Search using SQL Server 2005

I'm finding new blogs on SQL Server and B.I. all the time, and the latest is this effort from Jamie Mac.  He recently posted about MSN Search and how it is leveraging the features of SQL Server 2005 Data Mining to get better results to users.  There is a video on Channel 9 that talks about it (after about 14 mins).

According to the clip, MSN Search is now using Neural Networks (brings me back to my University days!!) to improve search results.
