The Mystery that is Volokh

I was struck by this comment to a post by my friend and colleague Eugene Volokh:

[Noting] Prof. Volokh's habit of posting about what, to an outside observer, might seem like random topics on the basis that the arguments contained therein are "unsound in a way that's generally worth exposing." I too have been baffled by what causes Prof. Volokh to take the time to refute something found in a random blog post, blog post comment, or even more obscure source.

Ditto. But those posts are almost always among his most interesting and provocative.
