RevCanonical is url shortening with a twist. Instead of creating its own super short versions of links, it checks to see if the link owner has published a shortened version of the given page using HTML link element. If not, we just return the original URL. And you should bug the link owner about providing a better alternative.
longereply.com to convert any section of text into a URL so you can then send this link via IM, Twitter, email? Can send very large peices of text. Use the command "longreply".
