Time for the obligatory mention of this month's Biblical Studies Carnival (the 23rd), over on Ancient Hebrew Poetry.
He also includes a post script, calling for more atheist or Jewish bibliobloggers. While I wouldn't deny the heavy presence of evangelical bibliobloggers (and the frequent debates pertinent only to them), I think his overall sentiment might reflect more what's on his blogroll than what's in the blogosphere. In many cases, I'd think the reason that so few non-Christians partake in some of the discussions isn't so much that we aren't here, or don't have a voice, it's that we simply don't care--that's not a dig at those who do, it's just that the subject matter of the "monologues" frequently isn't of interest to us (for an easy example, it doesn't matter how many times the Good Doc West mentions Zwingli, I'm still not going to read him).
Does Hobbins' sentiment, "It bothers me when Bible blogdom becomes a monologue among like-minded Christians," really hold to blogs such as The NT Gateway? The Forbidden Gospels? Hypotyposeis? The Busybody? The answer to all of these seems to be a resounding "no."
