I use delicious on a daily basis, and I feel that the problem it solves is very much alive. Maybe I am a bit of a power user, as I search and tag (and love the automatic tag suggestions) all my delicious links from a FF plugin.
But I believe it is still a solution for a very persistent problem, and as long as it solves it, it will be able to survive very well in today's web.
