EXCELLENT "clip n' save" RT article from April 2, explaining how Russia forcing Western nations to buy gas in gold-backed rubles will affect the world's economy. It's divided into handy sections:
What does it mean for oil?
What does it mean for the price of gold?
What does it mean for the ruble?
What does it mean for other currencies?
Among other things, it explains how logically this will "blow up" the paper-gold market, and also keep banksters from artificially depressing the price of real gold, which IMO is about damned time…
