I was just thinking a hackernews userscript that tossed these up somewhere in the layout might be good, given the audience. The core of it's just picking a random quote from an array so it should be simple. You could select lines or quotes from users and add them to the queue with LocalStorage or something.
All it does is take a random quote from the array and stick it in an extra table row, and there's a link that alerts text selected by the mouse (which is currently pointless) and I need to do all the localstorage stuff but yeah.
I am now apparently working on this...
