The Dangers of Blogging

Greg Mankiw is worrying that blogging might keep "extaordinarily talented individuals" like, e.g., Greg Mankiw, from doing important work in the world (link).

I have to admit, I have not hitherto worried about that problem myself. I do, however remember Molière (link):

Writing is like prostitution. First you do it for love, then you do it for a few friends, the next thing you know, you are doing it for money.
