Track your links with Tr.im

There are a multitude of URL shortening services out there, but Tr.im offers a unique feature; if you register (for free), you can create unique shortened URLs and get statistics about how many clicks you get, plus other standard user info such as platform, date, and whether it was a human or a bot—all extremely useful for people using things like Twitter for business purposes (or just info junkies such as myself).
