Gilded learning materials

I want to get a discussion going about the best sources for learning about metals trading specifically. Excellent material on general trading is welcome, but I am trying to get up to speed in the metals markets. Any medium is fair game: books, podcasts, blogs, videos... Anything that has helped you become a better metals trader!

The next on my list: Stack Silver Get Gold

There's a need for better books in this area. I could give you a great list of recommendations for general trading, econ, options, etc., but I've yet to find anything outstanding for metals.

I've been struggling to find good materials specific to metals. It seems like most of the classic gold bugs tend to lean toward paranoia. The hunt continues... I shall update here as I find anything quality.
