Introduced by U.S. Sen. John Cornyn, a Texas Republican, the “Internet Stopping Adults Facilitating the Exploitation of Today’s Youth Act,” or Internet Safety Act, states that “a provider of an electronic communication service or remote computing service shall retain for a period of at least two years all records or other information pertaining to the identity of a user of a temporarily assigned network address the service assigns to that user.”

Sounds a bit broad, doesn’t? And indeed, privacy advocates say that it applies not just to the Wi-Fi access points of Internet service providers, but to those of libraries, schools, businesses and individuals as well.

To mine. And to yours.

An unsettling thought. Said Greg Nojeim, senior counsel at the Center for Democracy & Technology: “[This is] invasive, risky, unnecessary, and likely to be ineffective.”

Perhaps. But it’s for the children. “While the Internet has generated many positive changes in the way we communicate and do business, its limitless nature offers anonymity that has opened the door to criminals looking to harm innocent children,” Sen. Cornyn said Thursday. “Keeping our children safe requires cooperation on the local, state, federal, and family level.”

Facebook really is That company. Which company? That one. That company that shows up once in a very long while–the Google of yesterday, the Microsoft of long ago. That company where large numbers of stunningly-brilliant people congregate and feed off each other’s genius. That company that’s doing with 60 engineers what teams of 600 can’t pull off. That company that’s on the cusp of Changing The World, that’s still small enough where each employee has a huge impact on the organization, where you think about working now and again, and where you know you’ll kick yourself in three years if you don’t jump on the bandwagon now, even after someone had told you that it was rolling toward the promised land. That company where everyone seems to be having the time of their life. … I’m serious. I have drunk from the Kool-Aid, and it is delicious.”

– Facebook manager Justin Rosenstein, June 15, 2007

Facebook manager Justin Rosenstein once described the social network as “the Google (GOOG) of yesterday, the Microsoft (MSFT) of long ago.” Today, Rosenstein perhaps views it as the Facebook of So Totally Last Week because he’s leaving the company, along with departing Facebook co-founder Dustin Moskovitz. Together the two hope to develop some sort of new extensible enterprise productivity suite, something that will be “to your work life what Facebook.com is to your social life,” according to a post on Rosenstein’s Facebook page.

“We see this new venture as very complementary to Facebook,” Rosenstein explained. “We hope our products will become to your work life what Facebook.com is to your social life. Our software will use Facebook Connect as the default option for identity and authentication. Our user interface will adopt many of Facebook’s conventions, creating a seamless and familiar experience for current Facebook users. And if our new development tools turn out to be useful, we hope the Facebook engineering team will come to adopt them.”

The departures are a blow to Facebook, which has been suffering something of a brain drain recently, and more specifically, to CEO Mark Zuckerberg who founded the company with Moskovitz while the two were undergraduates at Harvard.
