No, they aren't.
Of course, Brian went on to ask the question in a manner more focused on blogs about the Bible run by laypeople and students. With more professors and professionals blogging, there may well be a decline in interest in some biblioblogs. But that would not represent the death of biblioblogs in general. And I suspect that, as long as someone has interesting things to say and an entertaining way to say them, there will be room for their blogs. Some of the most popular blogs – and some that seem to definitely be increasing in popularly – are not ones that even claim to offer some particular expert perspective.
What do readers of this blog think? What is the future of biblioblogging, if indeed you think there is one?
And do we need (with HT to Rod) a song to express this – a version of the famous children's song from church, with lyrics that say something like “Blog's not dead NO it's still alive…”?
