Hey, look! Another post from your blog!
SHOCK!
Perhaps I do it because I am not great enough to act as humbly as you consider appropriate.
Perhaps it's because after the ten or more hours I spend (between our daily internet and electrical outages and thunderstorms here) each day researching, generally trying to keep informed and writing I do not have enough time to do more than to read articles posted by others and to comment on them.
Or perhaps it's because I am simply a jerk.
Whatever pleases you and helps to enhance your self-image is fine with me; if it's not too much trouble for you, even your occasional substantively derogatory comments would be welcome.
Oh, come on, hum, lighten up.
The Krugman cartoon is priceless.
