Sure, but if somebody made > terminate URIs properly in one of the forks, it might osmose into HN. One can dream. You can tell that they're still using the same broken code that is in the old ARC distribution.

HN actually has many improvements from the last Arc distribution, speaking as a person who runs my own fork of Anarki and used to run my own fork of the Arc distribution.

Unfortunately, they can't distribute their improvements, due to not having the time or YCombinator not wanting to give up some of their "special sauce" for dealing with spammers and vote rigging, etc.

And for what it's worth (which is likely very little) as a contributor to Anarki, support for > is on my list of things to add to sometime in the (mumble) future. Not that it will do HN much good.
