As it happens, I have been know to look at my blog stats from time (!), and today I noticed something odd in the referrer stats:
A referral from Amazon. WTF?
The link goes to a book detail page for a book about Wikipedia:
Scrolling down a bit, I found this:
A blog post syndicated in the product page from one of the book’s authors that linked to my post on Data Scraping Wikipedia with Google Spreadsheets.
My immediate thought – is there any way we can blog info about courses that use set textbooks back into the related Amazon product page?
OUseful.Info, the blog... 
Did you try it? Is there a way to blog back into the related Amazon product page? If we could, it would be wholesome.
