Whenever you use any online service, especially one without a proven business model, you should always ask yourself “is the benefit of using this greater than the cost of it vanishing in a year’s time?”
Can we get an export of our DATA, eg. which tr.im urls goto what fullsize URLS?
So that I can rewrite the thousands of links in my blog which point to tr.im soon to be nowhere.
I’m pretty sure this isn't the last URL-shortening service to be closing its doors over the next year or so.
