Something for me to think about
Because blogging is such a personal pursuit, with strong and immediate ego-rewards, it can be irrationally seductive, particularly to highly competitive overachievers. The hazard - and this applies as well to disciplines beyond economics - is that extraordinarily talented individuals may end up, like lab mice drinking sugar water, spending more time blogging than they should, even though their comparative advantage is smaller in blogging than it is elsewhere. Distorted by noneconomic but nonetheless powerful rewards, the idea market would become less efficient than it should be, and we'd all suffer as a result. The real danger, in other words, may not be that the "lemons" - the "tolerable bloggers" - will take over as the mainstays of the blogosphere but that they won't.
Please stop blogging, Greg Mankiw. You have better things to do.
