Karl is an economics and business guy—that is where I learn from him.
Exactly.
I learned much about economics at the knee of Karl after 2009 - enough to spot econoklowns like Kruggie when they start spouting BS.
I was registered there and commented quite a bit until he changed the site.
Glad I didn't re-register, because he bashed Trump all through his term, and I would have gotten The Ban-Hammer for explaining realpolitik to him.
I still check in several times a week, but I miss The Bar.
