After relying heavily on fixed — and thus vulnerable — Web sites until early 2002, al Qaeda quickly switched to hiding its online operations within more legitimate bulletin boards and Internet sites offering free upload services or connecting through such popular social network sites as Orkut and MySpace.

Now on the run, bin Laden's organization is even more virtual, which often means more dependent on the World Wide Web to spread propaganda and plot operations.

It is also one of the main reasons why, despite the many blows that it received since 9/11, many analysts believe the organization's operational capabilities have not truly diminished.

Law enforcement officials in Europe report that the number of such Web sites went from a dozen on Sept. 10, 2001, to close to 5,000 today.

While only a handful are currently operated by al Qaeda officials or militants, they serve a crucial purpose by "spreading activation" and nourishing the outrage or the global Muslim community, therefore laying the groundwork for al Qaeda's fundraising and recruitment activities.

Take, as a case study, the most instantly iconic photo to emerge from the bombings: a hazy picture of a man in a crowded, eerily lit subway tunnel, holding a handkerchief to his mouth. That picture was taken on a camera phone by Adam Stacey, by no means a professional photographer, who happened to be on the subway train that was hit in a tunnel outside the Kings Cross tube station. Stacey instantly beamed the image to his friend Alfie Dennen, who runs moblog.co.uk. Dennen published the snapshot with a Creative Commons license permitting anybody to reprint it provided Stacey received credit for the photo. From there the image was picked up by picturephoning.com and then Wikipedia, the online encyclopedia that is edited by its readers, followed by Sky News, the Associated Press and finally the BBC and the Guardian newspaper. It has since been everywhere.

What happened Thursday is not done happening yet, nor will it be for a very long time. But one lesson that may already be gleaned is this: it is no longer newspapers, as the old maxim goes, that write the first draft of history. Cable news may offer instant images, but it has always been the role of the written word, meaning newspapers, to capture fleeting events and distill them into historical record. But by the time the first editions of print newspapers hit newsstands Friday morning, citizen journalists had already written that first draft, and in some respects the second and third draft, online. Factoring in Wikipedia's coverage of Thursday's terror, you might even say today’s papers are finally getting around to offering history’s 2,801st draft.
