unique hazards may exist, We can save Delicious, but probably not in the way you think:

Donating Delicious to the Library of Congress or the Smithsonian

Now we’re getting closer. While it is folly to assume either of these institutions could take over Delicious and keep it running as a viable service, it does seem like they would be interested in preserving the Delicious corpus and making it available for research.

I love Delicious for many reasons, but chief among them is that it is the Internet’s memory storage device. In the 7+ years of its existence it has recorded the collective online journeys of millions of users during a time when the Web was evolving dramatically. Those memories are irreplaceable and have enormous value both to their owners (the users) and to society.
