Brewster Khale of Wayback Machine and Internet Archive was quoted by the NY Times today when asked to comment on all of the “junk” he must be archiving along with all of the “worthwhile stuff.”

From Unseemly to Lowbrow, the Web’s Real Money Is in the Gutter

Brewster Kahle, who has created a large Internet archive he calls the Wayback Machine, which contains several times the amount of information in the Library of Congress, said that the number of questionable sites is beside the point so long as search engines do their job.
“We don’t worry about how many pages that I don’t care about are in the Internet archive,” he said. “What you do care about is, `Does it have the pages that I want?’ ”
He acknowledged, however, that “we haven’t done a very good job of putting the good stuff up there” on the Internet to dilute the bad, and that as a result today’s leaders “are shortchanging the next generation.”
…To Mr. Kahle, the Internet’s diversity, good and bad, means that people will find the information they want, as narrowly and as deeply as they care to explore it. While he, too, would like some method to control the spam that flows into his e-mailbox, he said he preferred a complex ecosystem to a monoculture as bland and regular as a suburban lawn.
“I grew up where almost everybody could sing all three verses of the `Gilligan’s Island’ theme song,” he said. “I don’t want my children to grow up like that.”

By JOHN SCHWARTZ
Life is good at the bottom of the cyberspace pit.

The company sold pills via the Web that promised to increase penis length, bust size and body height.
