The other day, while "travelling Deutsche Bahn", I read an article in the venerable Frankfurter Allgemeine Zeitung. To my slight surprise, it included a link to some government document in form of a tinyurl.com URL - (http://tinyurl.com/cr8qso). As I had no internet acccess at the time I read the article, I had to defer checking out the link to some later time. Then I began to wonder how stable those URLs are compared to the stability of the link they service and of the newspaper article itself. The description of the link would probably allow for some targetted google searching, but is it not the responsibility of the newspaper to allow their readers to research the link in a couple of days, months or maybe years? Does tinyurl.com maybe have an enterprise feature where they guarantee long-living links to newspapers and similar customers?
