Blogging can be used as yet another way for the members of the body to build each other up. Like, what if we had a City Vineyard blog, where Dave could post random daily thoughts, and others in City Vineyard could join in?
Other faith communities are doing this; googling “church blog” brings up some interesting examples.

I would rather see an online discussion forum, where we (as a church body) can discuss the message of the week, providing personal insights and especially real-world impact that we see or that comes from our applying the message.
