ShortURL Auto-Discovery Twitter Bookmarklet

Tweet-this-Bookmarklet

Recently I've created a boomarklet to post links quickly to twitter using URL-shortening. The main feature was that you don't have to login on 3rd party web sites because it takes you to twitter. But now there's some more improvement: The new bookmarklet looks for a tiny url on the website itself in a <link rel="short_url"-Tag> (thanks to Snaplog).

To install just drag this link in your bookmark toolbar and you're done:

tweet this

Since there are not too many pages that implement the short_url tag, it falls back to is.gd shortening if it couldn't find one. To test it navigate to a page that offers a short_url for example: http://robert.snaplog.com/:E39/brooklyn_not_ark

Edit 2009-10-22: New Version

The new major version Twitter Bookmarklet III is available.

New in Version 0.9.3.5:

Since the short_url could lead to confusion with URL/URI and has the underscore I've updated the bookmarklet again to support rel="shortlink" too, which seems like a better term. There was of course some discussion.

New in Version 0.9.2:

The bookmarklet has been updated again to allow the short_url keyword to be one of a space separated list. This means it works now on arstechnica.com.

New in Version 0.9.1:

I had to update the bookmaklet to support relative URLs as used by http://www.geograph.org.uk/photo/19. In Javascript element.href returns the full, absolute url like http://e.com/absolute etc. while l.attributes[x].nodeValue may return something like /relative.
