I'm really Twitter illiterate, and would appreciate guidance - do you revoke access by unfollowing Amazon, or is there somewhere on the Amazon site that you have to revoke the permission?
ETA - Never mind! I figured it out. For anyone else who's wondering, go to your "Applications" tab in your Twitter account settings to revoke Amazon access.
