Where is the best place to get started in the Microsoft world?

I've recently been getting back into Windows after a love affair with Linux and Android (from around say a couple of months after Windows 7 to the consumer preview of 8), and I got well versed with the Android community (who the people are, what blogs to read, what forums to follow, etc). I'm wondering as to where one should start to get well versed into the Microsoft community? Links, blogs, forums, people, sites, etc would all be helpful.
