… all tr.im links will continue to redirect, and will do so until at least December 31, 2009. Your tweets with tr.im URLs in them will not be affected.
We regret that it came to this, but all of our efforts to avoid it failed. No business we approached wanted to purchase tr.im for even a minor amount. There is no way for us to monetize URL shortening — users won’t pay for it — and we just can’t justify further devleopment since Twitter has all but annointed bit.ly the market winner. There is simply no point for us to continue operating tr.im, and pay for its upkeep.
This is a sad and unfortunate turn of events. I recently switched to bit.ly but never lost any love for tr.im.
