And the URLs are dramatically shorter than a character or two-- for example:
http://➡.ws/껻 (6 chars after protocol)
http://tinyurl.com/aqehn8 (16 chars after protocol)
http://ri.ms/9i0 (9 chars after protocol)
It only beats our own ri.ms shrinker by three characters, but that's still something people might consider. And because it uses unicode, it will be a very long time before it moves beyond even 2 character suffixes.
Anyway, thanks for the feedback. :)
