I just want to point out that anyone can help the Archive Team by running an "Archive Team Warrior". It's a virtual machine which scrapes things that need to be archived. Currently Posterous, Formspring, various URL shorteners and of course upcoming.org (in testing).
It's really easy to set up and I would encourage anyone remotely interested to give it a try. More info & download: http://www.archiveteam.org/index.php?title=ArchiveTeam_Warri...
