I'd really like to see the debate between Krugman and Bob Murphy happen. So I thought of this username for the New York Times: krugmandebatedotcom would gain the attention of Krugman and the followers.
I've had two comments posted out of six. The other four were comments regarding "debate Robert P. Murphy." I happened to see the something below the comment box. "Comments are moderated and generally will be posted if they are on-topic and not abusive."
So I'm just using reverse psychology now just to gain attention to my username.
