Thanks, that looks quite interesting. I have already found a book I might like.

> I'm adding recommendations and products daily. Do you add the recommendations manually or do you use a crawler/API to copy the comment? How automatic is it?

Finally, I have two suggestions: You're only selling to people in the US. Maybe you could also add links to other Amazon domains (or use a service like geni.us)?

And how about linking back to the comment thread? Sometimes, a comment only makes sense in its context, and I couldn't find a link back.
