We’ve just added a bit.ly URL shortener destination. If you drop a URL on it, a shorter bit.ly URL will be put on your clipboard.
bit.ly is probably the best URL shortener as it lets you track how many clicks your URL has had.
As an example, here is a URL shortened with bit.ly:
To get stats on the URL, I go to:
Under my bit.ly account I can also choose whether I want stats for the URL to be public and see a listing of recently shared URLs. bit.ly can also be set to auto-tweet my URLs. Very useful.
Thanks to Sergej Müller for contributing this!
