I finally got the typo amazon sidebar working. Nifty thumbnails and riches beyond measure are now mine! Well, at least the thumbnails…

This is what you need to do. Enable the Amazon postprocessor in your preferred text filter (e.g. Markdown), which lets you write urls as <a href="amazon:0743253434">…</a>. (Note: I find that if you don't use double quotes it doesn't work) Then, set up the Amazon sidebar, which is straightforward. Handcrafted URLs don't seem to work, though it's possible a handcrafted URL of the kind generated by the Amazon filter would (e.g. http://www.amazon.com/exec/obidos/ASIN/0743253434/thefug-20).
