Rev=canonical URL shortening
I like Kellan's new URL shortening engine. It must be hard for perfectionists like him living in the mortal world ;)
Huh?
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.
Why?
URL shorteners are as problematic as they are useful. They create SPOFs, that over any meaningful timeframe are guaranteed to create data loss, eroding the historical record. And then there are the privacy concerns. And the usability ones. See also on url shorteners and Solving the TinyUrl centralization problem.
