Ken Levy has a blog post entitled From product manager to product planner where he writes

After working as a product manager in the developer division for the past 4.5 years, I've decided to accept an offer to work in a new position at Microsoft. Starting in March, I will be a product planner working on developer community efforts in a new group within the Windows Live division.

I'll definitely miss the regular interaction with VFP team members and the great Visual FoxPro community. I've also had great experiences working with the WebData XML team on the XML tools story for Visual Studio 2005, doing some community work with the VB team, and helping with content for Channel 9 both in front of and behind the camera. I expect to continue to do interviews and be interviewed for Channel 9 from time to time ongoing since it is such a great site for community efforts and transparency.

I can't say much about my new role just yet. To get an idea of just some of the developer centric things I'll be working on in the Windows Live team, check out the recent 21 minute video by Robert Scoble on Channel 9 interviewing my new manager, Windows Live group product planner Scott Swanson...MSN Messenger APIs

Given that I was one of the folks who pitched Ken on coming over to work on the developer platform activities in Windows Live, I'm glad to see him come over. When I was on the WebData XML team I saw Ken do great work in evangelizing the XML tools we built for Visual Studio 2005. I can't wait to see what he does for the various APIs we plan to develop around Windows Live.
