ptorrone wrote to mention an article on the MAKE blog, where the author theorizes that perhaps someday instead of frequent flyer miles we'll get WoW gold or EQ plat as a reward for using our credit cards. From the article: "It's not a matter of if, just when - credit card companies, Pay Pal, Amazon, eBay and the individual "gaming" companies eventually bridge the real and virtual currencies with loyalty programs and private label credit cards - there's too much money out there to -not- to do this. This 'demographic' is the battleground. The more you spend, the more you earn, sorta. Virtual $ isn't a crappy electronics doo-dad, it's just a number in a computer. Maybe you'll get some discounted airline tickets when you hit level 60 too, you deserve it! Earn your way to a new graphics card, why not."
