I just noticed on the Amazon Associates site, you can build a referral widget linking to Your Media Library (books, movies, and music you buy on Amazon and choose to share).
I like the idea that a person with good taste and blog readership could get a kickback from their purchase stream.
This blog is hosted by WordPress, and the widget uses an IFrame, which is verboten. Amazon, why not supply an RSS feed? Or let me insert my associate ID into the links on my permalinked page. It’s sending people to Amazon regardless.
