There are no more throw away resources. A lot of the shortened urls are going to twitter, of course, but those tweets are copy/pasted into blogs and those are copy pasted...

The companies may be around forever too. The web archive catches as much as it can. I don't really know if anything on the internet will ever go away anymore forever.
