Dan Gillmor brings up a very serious privacy concern about Amazon.com’s new Honor System program in his column. When you visit a page that contains a “donate through the Honor System” button that’s served up by Amazon.com, your Amazon.com cookie is sent back to their server, letting them know which sites you’re surfing. If their Honor System program becomes pervasive, they’ll be able to compile a dossier of sites you visit, even if you never donate to any of them. Yuck.
