Is Loading Up On Silver A Good Investment Idea?

Some opinions about investing in silver from this USA Today article:

[...] If you're going to bet on silver, it's best to treat the bet like you would a position in a very volatile individual stock. Make sure you know what price at which you'd sell. And if the price falls to that level, don't ask questions and get out.
