I saw a picture floating around the web of Mark Zuckerberg with his laptop in the background and his webcam was covered, so it sounds like a good idea. But what made me cover mine up was the fact I don't ever use it and our IT guy at my workplace said he sees people on our work laptops sometimes when helping them with technical problems, and he has seen things he cannot unsee... It creeped me out so both my home and work laptops have their cameras covered up!
