A New Kind of Conversation is an interesting experiment:

This blog-book will discuss what a postmodern evangelical faith looks like. The blog format will make it possible to allow you the reader, to participate in the writing of both the blog and the eventual published book to follow by Paternoster. Be a part of this experiment in conversation by adding your voice to the discussion.

Cool. Kick off with What is “Postmodernism?”Bruce Ellis Benson and Spiritual Formation in a Postmodern Context — Brian McLaren.
