ur.ly - the underappreciated URL shortener

I say underappreciated because it has all the good things you could want of a URL shortener (it makes URLs very short, is fast, scalable, and should last), yet everyone I know is using bit.ly, ur1.ca, or, worse, tinyurl.com.

The URLs generated by ur.ly use capitals, lowercases, and numbers, and the domain is 5 characters (u, r, ., l, and y), making it give one of the shortest URLs of any service (only one I know of that gives shorter is to., which doesn't work everywhere). It's also hosted on Google App Engine, so it'll be reliable and long-lived.

For comparison...
