I think you will find it is rich with valuable information. And the St. Louis site isn't unique among Reserve Banks. All the Reserve Banks and their presidents, as well as the Board of Governors, are committed to making information easily available. Over the years I have known many FOMC members. I can tell you that they are highly qualified and also quite approachable and accessible.
Monetary policy is indeed complicated, as is nuclear physics.
I find nuclear physics puzzling, or mysterious, simply because I don't understand much about it. Monetary policy is not inherently mysterious, anymore than is any other subject. But it does take a concerted effort and accumulation of knowledge over time to understand what the monetary policy debates are all about. One of the enjoyable things about this subject matter is that it is possible to go far into it without being a trained economist. And it is also true that a person such as myself who has been following monetary policy and macroeconomics for the whole of his or her professional career can still find endless fascination with the subject.
