Sorry, wasn't me. I'll upvote you to equalize the downvote :)

And I agree with your reasoning - in another post that I had an Amazon affiliate code I remembered to put a disclosure, however this time I forgot.

On a reasonably related note, I found out a few days ago that StackOverflow and the StackExchange network of sites automatically insert their affiliate code into Amazon and presumably other sites links.

edit: and I just got back, so can do any edits you would suggest to the article
