"Break the web"? "Evil"?
Have you been listening to Jacob Nielsen again? What next? Links should be blue? Nav should be on the left?You're already rewriting links. All that affiliate malarkey is far more breaky-webby* than sticking in a perfectly valid attribute to open a link in a new tab, based on a user preference that says "I'd like that please". If it is so evil why were you doing it until last week.
*technical term, honest.
Seriously... not going to break the web. No way, no day. Target attributes are evil, and they're not coming in.
