I'd like to see one that can deal with thousands of bookmarks all in reach, through whatever the developer thinks works. Say it's tags. Say I can write import rules so that all HN posts are tagged HN, then I can search for ruby and check that they are all about the language rather than the gem then tag them ruby.
