It's being widely reported that MSN switched to its new, home-grown web search engine. Congratulations to Brady, Erik, Mez, Chris, and the rest of the MSN Search team.
MSN promises their search will offer a "more personalized search experience" than the competition. Interesting that MSN sees personalization as their differentiator.
Chris Payne (VP at MSN Search, ex-Amazon.com) posts about the launch on the MSN Search weblog.
