Tweet Canonical
Further to my last post, Lachlan Hardy has gone one step better and written a bookmarklet that will find the RevCanonical link (if it exists) for the page you’re looking at:
I wrote a bookmarklet to scratch an itch. It parses the current page in your browser for a RevCanonical link and sends that to Twitter as the base of a tweet. I mostly plan to use it to tweet about Flickr photos but you can use it on any page that has a RevCanonical link.
You can install it by dragging this link to your bookmark toolbar: Tweet Canonical.
Works a treat and not only for Flic.kr photo pages.
