I wasn’t aware of this ranked listing of “biblioblogs.” It’s not complete—some of the big name NT scholars’ blogs are not listed here, and I’m sure they would rate a fairly high place in the list (e.g., Darrell Bock, Andreas Kostenberger, Dave Black, etc.), so take it for what it’s worth.
The reason I noted the list is that this blog (NTResources.com/blog/) is listed.
It’s number 10. Not sure the value (or basis) for the list, but it’s interesting none-the-less.
