One of these years I want to open-source a stripped-down version of that Chrome extension, or better still make it an optional JS client that people can opt into. It's handy for browsing HN, if you like keyboard shortcuts and don't mind spawning tabs. Anybody know if there's a way for regular JS to spawn tabs, if the user is willing to give it the right permissions?
(which, FYI, is functional though non-pretty, just like the HTML)
