Implementing this option (as an official HN feature) could be done entirely in Javascript (meaning no need to worry about building more shit into the server) and completed in under an hour. It would be cool if there were an "HN Labs" that suggested feature submissions and allowed users to add them to their accounts as profile extensions. Setting up HN links with _blank is also a trivial solution to implement on your own though.
