I know this is a duplicate, I feel that in this case the situation merits it.  The discussion over here : <a href="http://news.ycombinator.com/item?id=1069377" rel="nofollow">http://news.ycombinator.com/item?id=1069377</a> : is concentrating on the idea of discovering (an approximation to) your internal HN id.<p>Much, <i>much</i> more interesting is the potential for tagging items.  If just 1% of people took the time to tag things then it could become a really useful resource.  It might even become my first portal to HN.<p>Two suggestions: Please can we have somewhere a list of used tags, and please can it not show dead items?
