I love this: if you put a + (plus) sign at the end of any bit.ly URL, it immediately goes to the info page for that link, displaying all those juicy stats, as opposed to the link itself.
For example, instead of entering http://bit.ly/7NBhid, which is the shortened link to my Top 10 Most Popular Twittercism Posts Of 2009 article,Â I would enter http://bit.ly/7NBhid+, which takes me straight to the data. (By clicking on each of these you can see the difference.)
This is super-useful. Try it.
