Today one of my colleagues at the Institute and I finished up a draft of a piece on the future of biomimicry. We've been working on it for a while, and had divided up the piece into several sections. But when it came time to write the opening and conclusion, and do the editorial work necessary to make the pieces flow together, we decided to try something new: we put it up on Google docs (formerly Writely), and worked on it together.

The experience was a very interesting one, for a couple reasons.

First, the technology. Google docs has a basic word processor, and while it doesn't do footnotes, it has most of the essentials for styling and structuring documents (though most people mistake the former for the latter). It also has a pretty good revisions tracker, which is a cross between the "track changes" functionality in Word, and the view changes feature you see on many wikis.

I suspect that when people design (or start to play around with) such systems, they imagine the collaborators being separated by oceans and time zones: that the real benefits will come to coauthors in Berlin and Berkeley, or Paris and Perth. And for lots of groups, that's probably a plus. But what struck me, as my colleague and I were working on our article, was how valuable it was for the two of, even though we were right across from each other. We'd brainstorm a transition, or talk about how to restructure a paragraph; one of us would make the changes, and save the version; we'd hit refresh, look at it on our respective machines; and rework it until we had it right.

In a couple hours we had written as much as we'd each written in the previous month. Why? In part, writing together serves to tighten attention. I'm easily distracted, and can hit Google to look up some very specific fact, only to find myself ten minutes later looking at a Web site about animal pictures on the London Underground.

It also serves to eliminate some of the rationalizations that slow traditional multiauthored pieces. There are always turns of phrase or pieces of argument that really need to be worked out with your co-authors; when you're writing alone, it's easy to put those sections off until later, and tell yourself, "Well, I can't write the next paragraph until we work out that transition. I wonder if there are any new cat videos on YouTube?" When your coauthor is right beside you, and it's easy to make changes right in the document, the bar to completion gets lower.

It's also much easier to make changes directly onscreen, in a way that everyone can see, than to put edits on a printed page, which have to then be carried later (if you can remember exactly what they meant).

Of course, the technology could be a little better: having automatic line or paragraph numbering, for example, would make it infinitely easier for collaborators to stay on the same page (as it were). Instinct suggests that this isn't hard to implement, but if you assume that coauthors are going to be working asynchronously and at a distance, you don't need it.

But that doesn't detract from the big point: the system may facilitate collaboration at a distance, but it supercharges collaboration in person. More broadly, I suspect that this is where the really big gains in collaborative and social software will be made in the future: not in teams whose members are on opposite sides of a continent, but teams whose members are on opposite sides of a coffee table.
