While this may not be one of the deepest posts you've ever seen, it could be one of the most useful.  My team consists of some of the smartest most Microsoft tech savvy people you could ever meet AND they want to meet with you!  They have blogs, they tweet and they hold office hours that you can schedule with them.  If you're in the western USA they probably are in an office close to you OR visit your city at least a couple times a year.  If you ever have any questions about the Microsoft platform for developers or infrastructure, reach out to your local evangelist and they will point you in the right direction.
