I suppose it's a good project with good intentions, but it's still only as useful as the content it points to. Take, for instance, Geocities - the amazing free platform where everyone was experimenting with websites at the same time. It's all gone. A permanent URL helps not-at-all. True, the Web Archive has a lot of old Geocities pages cached, but most of the time I find something missing, the content is gone. It has nothing to do with the wrong URL. That said, it's a nice way to claim a "permanent" URL for say, yourself. It lets you change domain names and whatnot in the future. Still, I don't mean to downplay the good intentions. I just wonder what the half-life of the database is - that is, before half of all claimed perm URLs point to nothing.
