There are a very few things at which I can call myself an expert. Mostly I know a little bit about a lot. And the little I know is generally just enough to get me in trouble with someone else who knows more.
BUT, that doesn't keep me from pretending I know a lot about anything in particular. My latest infatuation is economics. I've been thoroughly enjoying Arnold Kling and Russ Nelson.
Honestly, I don't really think that (m)any people will read this, but if you do, you've been warned.
