I am using it primarily to shorten links back to http://alanhogan.com http://alanhogan.com, and since I run both domains, I intend to keep both of them running as long as possible -- and when one goes down, the other becomes pretty much useless. But yes, I agree that it is important to intend to run these services forever.
