MARK GOODACRE has some observations about how the online Gospel of Jesus' Wife controversy is affecting peer review: The Jesus' Wife Fragment and the Transformation of Peer Review?
I like to post informal drafts of my work (usually conference papers) so I can get online feedback before peer review even comes up. Most of the time the best informal feedback I get comes from the discussion at the conference, but I've not posted anything online that would get the kind of attention and scrutiny that Professor King's paper on the GJW has received.
