One of the founding principles of the Web—not only the technology but the culture that has grown up with it—is that, as the New Yorker cartoon once put it, "On the Internet, nobody knows you’re a dog."
The policy that people are free to interact online anonymously—or at least using pseudonyms—is now under attack from social networking companies. Both Faceboook and Google, which in June launched a competing service called Google Plus, have cracked down on people trying to use pseudonyms rather than full identities.
"The Internet would be better if we had an accurate notion that you were a real person as opposed to a dog, or a fake person, or a spammer," Eric Schmidt, Google’s chairman, said at the Edinburgh International Television Festival last week. He was echoing Randi Zuckerberg, Facebook’s former marketing director, who declared earlier this year that, "anonymity on the internet has to go away."
These arguments are half right. Anonymity should not be banned in every corner of the Internet any more than it is in the physical world in democracies--it would breach civil liberties. But there are good reasons to discourage it. Most users would gain if anonymity were the exception rather than the rule.
Mr. Schmidt and Ms. Zuckerberg (whose brother Mark, Facebook’s founder, has attacked the use of multiple identities as displaying "a lack of ethics") have been criticized for their remarks. "The desire to clean up the Web, civilize it, and sterilize it, pisses me off. I hate it," Fred Wilson, a venture capitalist, wrote earlier this month.
The author’s attitude toward the Web anonymity is______.
