Suggest HN: Use target=“_blank” for external links

I'm not sure why HN doesn't do this, but I think it would be a better experience if external links opened in new tabs/windows instead of in the parent one. I always have to remember to middle click (or control-click) whenever I click a link. If the reasoning is the "tabnabbing" exploit, window.opener can always be clobbered, or the new tab can use a redirector (as FB does). (As a sidenote, for whatever reason, reddit doesn't use target="_blank" either. It's really annoying clicking an external link and losing my point in a huge comment thread.)
