Mailbag on the gold/platinum ratio

As I've suddenly become interested in platinum the metal (there's always a reason, no?), the mail received this morning from reader 'M' caught my attention and included this:

"....anything to read into the way gold bullion has been catching up with the price of platinum [?]..."

That got me scuttling off to the chartysites which led to this, a chart that tracks the price ratio of gold to platinum over the last three years:

 The ratio touched 1:1 back at the end of 2008 (wasn't THAT a fun time for the market?) and here we are again, closing in on 1:1. Now I dunno if that means anything, but it's interesting enough to put on the blog on a Sunday. 

Feel free to talk amongst yourselves.
