Economists Who Blog The Los Angeles Times has this piece on "slide-rule celebrities," about how economists who blog can attract a large new audience for their writing.

Nobel laureate Gary S. Becker and former Harvard President Lawrence H. Summers are among those who have set up blogs, which are typically part lecture, part journal and part college seminar, with reader participation expected.

Unless there's something I don't know, that's a reference to the New Republic blog, Open University, for which Summers is listed as a contributor but to which he has not, so far as I know, contributed.

So...kind of a mistake on the LA Times' part. But the piece does more accurately go into Harvard economist Gregory Mankiw's blog.

Who will be the first Harvard humanist to blog? And more to the point, why is is that at the world's greatest university, to borrow a phrase, the number of faculty bloggers can be counted on the fingers of one hand? Something is wrong with this picture.  ¶ 7:00 AM
