This is _not_ a copy of delicious, but I wrote some hours ago in a hurry:
http://selficious.appspot.com - It imported my bookmarks and I use it to manage
them and my future ones (add, edit, delete). The code is of course
opensource https://github.com/initpy/selficious I just need to clean it a lil' bit :) - Sure, there is so much to improve/rewrite
in it, but I have already have some ideas and yours are more than welcome!
P.S. This if my first post ever on HN so like japanese say: Dôzo Yoroshiku :)
