Is blacking out HN really necessary? Is there anyone here that doesn't know about SOPA/PIPA and the threat they represent?(I would ask the same about reddit but since I don't read the site I don't know if they have a broader demo) I suppose the whole point in doing the blackout would be to draw attention to people who haven't realized there is problem.
