Convenience is what you should be going for. If you're able to generate a short url for convenience, the chances of someone signing up later rather than saying "Signup just to try? fuck it" are higher.

Hell, when generating the url, just make a call to the api at http://tweak.tk so that you can display the short one side-by-side with the long one. Provided your codebase is well formed, a change like that should not be astronomical.

(P.S. Tweak.tk is really awesome. At least check it out.)

If you are going to use an URL shortening service, please go with one that is universally recognised by most tech people, such as bit.ly. I've never heard of tweak.tk and I've never seen it come across my Twitter feed.

The cool thing about tweak.tk is that it's operated by the .tk-registry and you're getting a free generated .tk domain instead of just a page on the domain of the shortening service. Jdyk56.tk instead of bitly.com/jdyk56

Wow, that's simultaneously cool and means I'm not going to use it. http://ddpor.tk looks too much like a link to a scam site.
