Barack Obama should be allowed to keep his BlackBerry at the White House, writes security rockstar Bruce Schneier. The roadblock is a legal one, but there's a cultural rift beneath it. Schneier was born in 1963. He writes like an Old, but thinks like the Youngs. Here's the core part of his essay:

Obama might be on the younger side of the generation gap, but the rules he's operating under were written by the older side. 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. And privacy isn't just about having something to hide; it has enormous value to democracy, liberty, and our basic humanity. 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.
