Bit.ly launched a new mobile site today and it's a pretty good combination of quick, easy and powerful. If you're browsing the web on your phone and you want to share a link with someone - why not jump over to Bit.ly mobile and shorten it first? That way you can easily get all kinds of analytics on who clicked through it, where they were and more.URL shortener
How to do it: Copy the code above, email it to yourself, open the email on your phone, copy the text of the code, then go to your phone's bookmarks. Edit one (you probably want to create something random just for this) and then replace the existing bookmark URL with the code above. Boom, you're set.
(Bit.ly HQ pinged me after I posted this and pointed out that if you log in to a Bit.ly account, there is a copyable code snippet in a bookmark page in the settings page. If you've got a Bit.ly account, that is all the easier.)
Either way - wouldn't you rather shorten links and get their analytics in 4 clicks than in 13? I sure would. Then you can go to the Bit.ly mobile site to view all the analytics. The toolbar method won't do the offline shortening that the new Bit.ly mobile site does, but that doesn't seem like a very big deal to me.
