Tim Bray's current job with Google centers around being an evangelist/catalyst for the Android platform. He's often accused of being a shill; his title is "Developer Advocate."
I'd argue that there is no better way to advocate to developers than to provide them with clear, concise overview documentation. Whether you're a coder, a forensicator, both, or neither (what are you doing reading this blog if you're neither?), you should check out his recent blog post, What Android Is.
