Gold still has made quite a great run, and still might continue as long as the carry trade does not unwind. Folks should have gotten into gold long ago though, as in around 800, or even better, 500. Even at these levels, it's smart to have some gold in your portfolio, especially when Bendover Bernanke is trying to murder the dollar.
Remember, an ounce of gold could purchase a Roman's toga and the rest of his wear back in the day. Today, that same ounce can still purchase a man's suit for work. Something to think about. It's certainly not worthless paper.
