Certain websites, such as Flickr, Amazon, and YouTube, offer their own URL shortening services for use on Twitter.
Usually, these shortened links come either from their post-to-Twitter feature or from one of their official Twitter accounts. It's not easy to transform one of their regular links into a shortened one yourself. The easiest sites, such as Amazon, simply require copying an identifier from the URL; other sites, such as Flickr, require extracting the short URL from somewhere in the document. This can be a lot of work to do manually.
So, I wrote a service to do it for me. Originally, it only did Flickr (the hardest one); later, I refactored it to support many different websites and their shorteners.
The current version supports these websites and their shorteners, listed here in alphabetical order by name:
MD5 and SHA1 signatures were created using EasyHash.
