The Magic Middle

Dave Sifry’s posted Part 2 of the State of the Blogosphere and this may be the most interesting chunk ever. There’s a lot more than just numbers in there; what particularly caught my eye was the notion of the “Magic Middle”, 150 thousand or so blogs with between 20 and 1,000 inbound links. These people tend to have a lot of very specific topical authority and to be, in general, good. Perhaps a new thing in the world?
