I had the mistaken impression it was against Amazon TOS to call attention to the links. After reading the TOS again, though, I think that would be ok from Amazon's perspective. There's a line between saying on the page "click these links so I'll make money" and saying the links are Amazon affiliate. Amazon TOS here: https://affiliate-program.amazon.com/gp/associates/help/oper...
Nice page, though. You should make money from it. How are you extracting the references to books from HN?
Thanks for your feedback! I use HNSearch API https://www.hnsearch.com/api to get submissions and comments. And then Amazon API to normalize and get meta info.
Yeah, just mention the affiliate links at the bottom of the page and have a little link "Click here to remove" and have it run some javascript to change the links.
