Learning Macro-Economics Web 2.0 Style

I have started viewing webcasts on macro-economics from the University of California Berkeley. This is to get a better understanding of economics, which I realized was lacking in my interactions with Marginal Revolution and other venues. I get the basics of supply and demand but I want to get a greater understanding so that I can better understand the issues this weblog has been considering over the last few months. Economics is apparently still the most relevant topic for this weblog. It also helps to understand how what I do as a government agent fits, effectively or not, into the larger economy and how I might make my own paradigm changes to fit outside the government sector.
