Blogging and Preaching

Ryan said in class yesterday that there's not much preaching in Alt/Emerging churches-- any teaching/dialogic interaction surrounding scripture happens on community blogs.

So what I wonder is this: in what way can blogging be seen (in both good and bad ways) as a natural outgrowth of the New Homiletic's (perhaps unaware) adaptation to postmodern philosophical and cultural considerations.

Could a paper come of this? "More than a Metaphor: Blogging as PostModern Proclamation."
