Ow.ly: The best way to shorten a bit.ly link

Wow.  I just shrunk http://on.msnbc.com/emW7NL (from bit.ly) to http://ow.ly/4iokZ on ow.ly, effectively giving myself more characters for Twitter writing.  While I like that they have an open API, I'm not a fan of having to use captcha every time I want to shorten a link.  The only way around that is to sign up for their service.  If you're like me and you are commitment-shy, this isn't the site for you.  However, if you want really short links and want to keep track of analytics, then maybe we can get over our fear of commitment together...Don't want to give up information...then sign in using Twitter. Ow.ly is the platform used by Hootsuite.
