This reality of the information age might be particularly stark for the president, but it's no less true for all of us. Conversation used to be ephemeral. Whether face-to-face or by phone, we could be reasonably sure that what we said disappeared as soon as we said it. Organized crime bosses worried about phone taps and room bugs, but that was the exception. Privacy was just assumed.

This has changed. We chat in e-mail, over SMS and IM, and on social networking websites like Facebook, MySpace, and LiveJournal. We blog and we Twitter. These conversations -- with friends, lovers, colleagues, members of our cabinet -- are not ephemeral; they leave their own electronic trails.

We know this intellectually, but we haven't truly internalized it. We type on, engrossed in conversation, forgetting we're being recorded and those recordings might come back to haunt us later.

Oliver North learned this, way back in 1987, when messages he thought he had deleted were saved by the White House PROFS system, and then subpoenaed in the Iran-Contra affair. Bill Gates learned this in 1998 when his conversational e-mails were provided to opposing counsel as part of the antitrust litigation discovery process. Mark Foley learned this in 2006 when his instant messages were saved and made public by the underage men he talked to. Paris Hilton learned this in 2005 when her cell phone account was hacked, and Sarah Palin learned it earlier this year when her Yahoo e-mail account was hacked. Someone in George W. Bush's administration learned this, and millions of e-mails went mysteriously and conveniently missing.

Ephemeral conversation is dying.

Cardinal Richelieu famously said, :If one would give me six lines written by the hand of the most honest man, I would find something in them to have him hanged." When all our ephemeral conversations can be saved for later examination, different rules have to apply. Conversation is not the same thing as correspondence. Words uttered in haste over morning coffee, whether spoken in a coffee shop or thumbed on a Blackberry, are not official pronouncements. Discussions in a meeting, whether held in a boardroom or a chat room, are not the same as answers at a press conference. And privacy isn't just about having something to hide; it has enormous value to democracy, liberty, and our basic humanity.

We can't turn back technology; electronic communications are here to stay and even our voice conversations are threatened. But as technology makes our conversations less ephemeral, we need laws to step in and safeguard ephemeral conversation. We need a comprehensive data privacy law, protecting our data and communications regardless of where it is stored or how it is processed. We need laws forcing companies to keep it private and delete it as soon as it is no longer needed. Laws requiring ISPs to store e-mails and other personal communications are exactly what we don't need.

Rules pertaining to government need to be different, because of the power differential. Subjecting the president's communications to eventual public review increases liberty because it reduces the government's power with respect to the people. Subjecting our communications to government review decreases liberty because it reduces our power with respect to the government. The president, as well as other members of government, need some ability to converse ephemerally -- just as they're allowed to have unrecorded meetings and phone calls -- but more of their actions need to be subject to public scrutiny.

But laws can only go so far. Law or no law, when something is made public it's too late. And many of us like having complete records of all our e-mail at our fingertips; it's like our offline brains.

In the end, this is cultural.

The Internet is the greatest generation gap since rock and roll. We're now witnessing one aspect of that generation gap: the younger generation chats digitally, and the older generation treats those chats as written correspondence. Until our CEOs blog, our Congressmen Twitter, and our world leaders send each other LOLcats – until we have a Presidential election where both candidates have a complete history on social networking sites from before they were teenagers– we aren't fully an information age society.

When everyone leaves a public digital trail of their personal thoughts since birth, no one will think twice about it being there. Obama might be on the younger side of the generation gap, but the rules he's operating under were written by the older side. It will take another generation before society's tolerance for digital ephemera changes.

This essay previously appeared on The Wall Street Journal website (not the print newspaper), and is an update of something I wrote previously.

The sky is falling! Trip Chowdhry, the analyst with Global Equities Research who claimed Red Hat was ‘rubbish and the entire LAMP stack is potty, too’ published some eye-opening predictions, predominantly negative, about tech business in Silicon Valley. Now Chowdhry claims that “almost every VC funded open-source company is struggling and will run out of money within the next six months.” (Probably not the most unbiased guy about open source) Matt Asay argues that organizations in general are struggling, but open-source companies are not that high on the list. (But are they high on the VC “axe” list??) He notes Alfresco, Pentaho and JasperSoft are some of the players with ‘millions in the bank and growing revenue.’ Asay also says Chowdhry has a responsibility to do real due diligence and not create myths. Take that, Chicken Little! (img from Disney-Clipart)

We’re not as far behind as we thought we were. Google presented the results of a study they conducted about how IPv6- capable “ordinary users” are at the RIPE meeting in Dubai a few weeks ago. Turns out Apple Macs drive IPv6 penetration in the US. Fifty-two percent of all IPv6 users in the U.S. own a Mac and use 6to4 (creating IPv6 addresses from an IPv4 address and tunneling packets) – making the US fifth in the list of countries using IPv6. Russia and France took first and second place with .76 and .65 percent IPv6-enabled traffic . The US is at .45 percent. Worldwide, 0.238 percent of Google users’ systems are IPv6-enabled and prefer to use IPv6 over IPv4.

Obama’s win = Google’s win? Apparently Google CEO Eric Schmidt and President-Elect Obama are very good buddies and “this terrifies Microsoft”. Now competitors are more on guard against Google’s growing empire and popularity. Although Schmidt was mentioned as a possible candidate for the country’s new national CTO position, he said he would not accept the post if asked. I guess that’s one less thing Microsoft has to worry about.
