Now that Delicious.com is wrecked, what's the best way to discover new sites? I've always been using the URL delicious.com/tag/tag1+tag2+tag3... to discover new and interesting sites within *very narrow and specific* subjects, e.g. delicious.com/tag/css+tools would only return sites tagged with *both* of the tags.

Now that Delicious.com is screwed, is there any good alternatives?

Ps: Not diigo.
