David Yates posted a good overview of the IndieWeb, Untangling the IndieWeb, where he concisely explains what its major protocols are supposed to do and how they work. But the most insightful part is his definition of the IndieWeb:

IndieWeb is about using the World Wide Web itself as a social network, through a set of open standards for communication and identification of content and people.

This post is especially welcome as the IndieWeb is still confusing, even for tech users.
