Why do you feel he does a terrible job? Does the Tea party do a terrible job? Does Dawkins do a terrible job? Did Marx, Nietzsche, Augustine, ... do terrible jobs? I don't doubt you can think of awesome people that others think are doing -- or did -- terrible jobs.
I'm glad someone says the things he says and I think it would be a loss if nobody said these things anymore. He's as much a visionary as Steve Jobs was, only his vision does not get carried out be a multi-billion dollar company, so he needs to keep spreading it with his mouth. He doesn't care about selling the vision, because that doesn't work in a world where many people believe Ayn Rand is someone with deep insight in how the world could and should be organised.
