I ask because I was recently rejected for my application (http://addonbuddy.com/). Their reason was "lack of original content." Here's part of the message I received:
"A part of our criteria is that your site has to be established with enough unique content. We rejected your application due to one or more of the following reasons.
- Lack of content which is original to your site and beneficial to your visitors
- Pages that are mainly empty when advertisement content is removed"
I like your site and think it offers a lot of value, but Amazon's affiliate program seems to favor blogs that have a lot of content. They can also be real sticklers about including certain text in your website indicating that you're part of the affiliate program.
