>Who selects the recipients, anyway- I mean, what is the name of the responsible person in MS? Is it Ken Levy?

No, it's not Ken Levy, although he has nominated people. In fact, he's the one who nominated me back in 2003. Anyone can nominate someone to be a MVP and it's decided by a panel of MS employees. Here's a Q/A about it from MS's MVP website:

Q3: How does Microsoft select its MVPs?

A3: Over 100 million people participate in technical communities but there are only about 3,500 MVPs worldwide. Outstanding technical community members are nominated by their peers, Microsoft employees, and MVPs. Each year a panel of Microsoft employees reviews the contributions of each nominee for quality, quantity, and level of impact on the technical community. Today's MVPs reflect Microsoft's global customer base and the breadth of its technologies.
