There's not an answer on there I could honestly choose if I'd taken that survey. I would have voted No. But I am on both services, I do understand how it works, and I am not scared of scams. I just don't see why I should - creating an account using an email address is also easy and by this point don't most people understand how it works? If they managed to sign up for facebook or twitter, they clearly do!
