His explanation (The Whats, Whys, and Wherefores) also goes a long way to explain why there are so many more postive reviews in the blogosphere than negative:
The idea is to skip the reviews of good but ultimately marginal albums I called Honorable Mentions. Though they filled out the column conceptually, these required a lot of work without commensurate musical reward, and since no blogger gets paid enough to put in that kind of time I intend to break myself of the habit (though there'll be exceptions).
I also like this part:
Forty years ago I dubbed myself the Dean of American Rock Critics. That was a joke with legs. The blog title Expert Witness is not a joke. It's a boast that in criticism, knowledge counts, and that I have a load and a half.
