How do you find what you want and how do you know it is true?

Judy Breck quotes Howard Rheingold on the information morass that is seeking what you want and knowing if it is true:

All of the world’s knowledge is in the air to be plucked down by our telephone. Of course it’s also all the world’s disinformation, misinformation, spam, porn, Nigerian frauds, urban legends, hoaxes. So how do you find what you want and how do you know that it’s true? Those seem like to me both extremely important questions today . . . .

The answer, says Judy Breck, is nothing less than to change both where we look and the way we ascertain truthfulness.
