Mimicking Twitterfall's Short URL Replacement | InsideRIA: "Due to the size limitations of Twitter, most folks will use a 'Short URL' service (like tinyurl.com) to post links. The problem with this is that it is impossible to tell where these links will take you. I noticed, though, that when I moused over these links in Twitterfall, they actually changed to their full version.
I opened up Firebug and did some digging and noticed that these replacements were being done serverside. With that in mind I decided to see if i could build my own version of this code with jQuery."
