Well, it’ll get the cause noticed. It will also screw over a lot of schoolchildren who’ve left their homework too late. I support the cause (SOPA and PIPA are, when not toxic, an appalling example of legislation by charisma and lobby, as opposed to meritocracy.) I also feel the WMF are entirely justified in blacking out the en-wikipedia to make a point, but I suspect this will breed a lot of resentment amongst thick people.
