Thomas Sowell's random thoughts, which are generally worth more than most people's fully developed ideas.
Psst. Hey...did you know that Paul Krugman used to actually be an economist who wrote worthwhile pieces, not the misleading polemics he generally writes today? (Yes I know I recently praised something he wrote, but it wasn't on economics and wasn't like most of he writes, i.e., it was good).
I have no words to describe how I fee about this.
