[tantek] jacky, I wouldn't use rel=alternate on a link to something you don't control / own, or rather, something where another party (owner) could change the content arbitrarily. E.g. exceptions might be an IPFS copy of the page/post, or perhaps more useful/reliable, the internet archive snapshot of your post, but only if you're already linking to it for other (user-centric) reasons
