Amazon Associates rejoice (or not) – Amazon just added a “Share on Twitter” link to the Amazon affiliate toolbar that appears at the top of every Amazon product page, with the Amazon associate’s Amazon affiliate tag (i.d.) already embedded in the link, so that when you hit the “Share on Twitter” link, the Amazon link to whatever product it is goes out to all of your Twitter followers with your Amazon associate i.d. already embedded within the link. We’re just surprised that it took Amazon so long to jump on this bandwagon! (Ah, the downside of the inertia of an enormous, publicly held company.)
