This week Google launched an ad campaign and Web site headlined “Good To Know,” according to a report at the Washington Post. Aimed at teaching Net users the basics of protecting their data in our increasingly social media environment, the campaign has ads appearing in “dozens of U.S. newspapers, including The New York Times, USA Today, and The Wall Street Journal, and magazines, including Time and the New Yorker.” People will also see the ads on Web pages and subway billboards in New York and Washington. “The campaign comes as Google and other technology companies face more questions and government pressure on privacy issues,” a Wall Street Journal blog reports. Proponents are calling it a public service, critics a PR campaign. A reviewer at PC World found the site to be a useful aggregation of Google’s online safety and security resources presented with “a fresh, easy-to-follow look and jargon-free writing.” Of course, like any such offering, it doesn’t go so far as to mention competitors’ products, such as alternatives to Google’s Chrome Web browser.
