Personal URL shortener for WordPress
Hum is a personal URL shortener for WordPress, designed to provide short URLs to your personal content, both hosted on WordPress and elsewhere. For example, rather than a long URL for a WordPress post such as http://willnorris.com/2011/01/hum-personal-url-shortener-wordpress, you could have a short URL like http://willnorris.com/b/FJ. Additional, if you have a custom domain for short URLs, you can shorten things further like http://wjn.me/b/FJ.
WordPress post IDs are shortened using the NewBase60 encoding scheme which is specifically optimized for brevity and readability, with built-in error correction for commonly confused characters like '1', 'l', and 'I'.
