Joe Carter at Evangelical Outpost has started a conversation on Breaking Out of the Ghetto. The main question he asks is how evangelical blogs can come together to be a greater influence on the blogosphere and by extension, the world at large. He's already taken a good first step by developing "The Church Directory" (the list of evangelical blogs on the right) as a master blogroll of evangelical bloggers.
Razorskiss took this discussion further with a series of posts on networking and traffic management. The latest installment is here.
The point of this whole discussion is to develop ideas about how Christian bloggers can work together to use the new and exciting medium of blogging to spread the Gospel.
Also, on a related note, Tod Bolsinger encourages pastors to start blogging.
