That article doesn't explain why silver has gone nuts. It basically takes two long pages to reiterate that it has gone nuts !
Besides, even if the author had some new point to make I wouldn't believe him because he writes:
"Silver is a totally pointless metal. (Okay, it does have some industrial applications — but even there it's generally substitutable. It's pointless, or at least a luxury, for ordinary people.)"
I'd like to see him try and substitute silver for something else in our papers and still have them perform the same. Oh, and my hobby is not some industrial exploit.
