The changes to whitehouse.gov are being used as an example of ephemeral digital content.
At the exact moment Barack Obama was inaugurated, all traces of President Bush vanished from the White House website, replaced by images of and speeches by his successor. Attached to the website had been a booklet entitled 100 Things Americans May Not Know About the Bush Administration - they may never know them now. When the website changed, the link was broken and the booklet became unavailable.
At the same time, the Obama administration is chafing under rules that don't allow them to use Facebook, gmail, Blackberries, and Twitter. Because of this pesky Presidential Records Act.
Suddenly, they have to relearn how to communicate, because the law has not caught up with the way people live. They are being forced to return to older technologies (or they will once those technologies start working properly), and abandon or become more guarded in their use of newer technologies.
Anyone else find the dissonance am(az|us)ing?
Seems that anyone who really wants a copy of that missing booklet will be able to access it via FOIA in a few years (unless it got wiped with all of Cheney's files).
Meanwhile, if the new guys find a way to stop being hobbled by the law, their digital content will likely be truely ephemeral, since they have become addicted to "newer technologies" that eliminate all expectations about data's preservation and privacy.
I think this is one case of the law not keeping up with technology that I can support. It might be more fair to describe it though, as technology not keeping up with the law.
