In certain corners of the Internet, it’s nearly impossible at the moment to avoid discussion of the death on Friday of Aaron Swartz, the “American computer programmer, writer, archivist, political organizer, and Internet activist”—to quote the current iteration of his rapidly-expanding Wikipedia article. Really, make that many corners of the Internet: from technology blogs to online magazines to mainstream newspapers, Swartz’s apparent suicide has been felt widely. And there’s good reason: Swartz’s career would be incredible even if he had not accomplished it all by the age of 26. But there is one reason why I’m writing about him now, in this space, and that’s because he was a Wikipedian.

Aaron Swartz (User:AaronSw) was not just any Wikipedian. He was one of the longest running contributors, first joining Wikipedia in August 2003 and making his last edit just the day before he died. Using a tool for the analysis of Wikipedia user accounts, I found the complete list of articles he created—a total of 199, including some fairly important ones. Among them: Civil liberties in the United States, United States Court of Appeals for the Ninth Circuit and
Arrested Development (TV series). He’s also the creator of dozens of articles about political and policy figures, writers, lawyers and government officials. Like most Wikipedia editors who are content creators, his Wikipedia interests matched his real-life ones. (He even edited his own biography at least once, although unlike most he left an exceedingly polite and deferential note about it.)

Speaking of content creators, in late 2006—around the time that I first began editing Wikipedia—Swartz published a widely-read and influential essay series, arguably titled “Wikimedia at the Crossroads”, after the first installment. However, it is best-known for its second, “Who Edits Wikipedia?”, in which Swartz analyzed the number of characters added by different editors, using code of his own writing, looking to answer his essay’s titular question. One of his most startling findings was that the contributors with the most edits across all of Wikipedia in fact added the least content to the analyzed page (Alan Alda, amusingly enough) while editors with fewer edits added more content:

Edit by edit, I watched the page evolve. The changes I saw largely fell into three groups. A tiny handful — probably around 5 out of nearly 400 — were “vandalism”: confused or malicious people adding things that simply didn’t fit, followed by someone undoing their change. The vast majority, by far, were small changes: people fixing typos, formatting, links, categories, and so on, making the article a little nicer but not adding much in the way of substance. Finally, a much smaller amount were genuine additions: a couple sentences or even paragraphs of new information added to the page.

…Almost every time I saw a substantive edit, I found the user who had contributed it was not an active user of the site. They generally had made less than 50 edits (typically around 10), usually on related pages. Most never even bothered to create an account.

Thus was born the observation that Wikipedia’s editorial community includes both highly active, long-serving facilitators and itinerant, subject matter-expert writers, and their interplay is crucial to Wikipedia’s continued development and its future. When we talk about the lack of new editors (or trouble retaining current editors) on Wikipedia, we’re still talking about this very subject—or at least we should be. The fact that Aaron Swartz was 19 or 20 at the time he wrote this nearly boggles the mind. What he might have contributed under different circumstances, and that we’ll never know what he might have done, boggles too.

As a brief aside, Swartz’s last sustained edits to Wikipedia in November were to Wikipedia’s bibliography of David Foster Wallace, a favorite author of Swartz’s and also mine. Swartz once even wrote a brilliant essay attempting to explain what happens after the end of Wallace’s 1,000-page novel Infinite Jest, which nearly everyone who reads it comes away persuaded and envious (and yes, I mean myself). Like Wallace, Swartz suffered from depression and wrote about it—more openly than DFW ever did—but couldn’t write his way out of it, and it eventually overtook him.

Aaron Swartz’s untimely passing is devastating for those who knew and loved him, and disconcerting for those who knew him only through his public career. You can read rememberences by many of them, including Wikimedia deputy director Erik Moeller (once the winner of a Wikimedia Foundation board election Swartz contested), Wikimedia board member Samuel Klein, and dozens of Wikipedia regulars commenting on the Talk page of Swartz’s Wikipedia account. And anyone who likes can add the following box to their own:

Many more remembrances can be found online, including comments from friends and acquaintances beyond Wikipedia, including Cory Doctorow, Lawrence Lessig, John Gruber, Matthew Yglesias, Matt Stoller, from his family, and a page for anyone who wants to contribute something. Sure, it’s not quite “anyone can edit” like the online encyclopedia he cared deeply about and strived to make better, but it will have to do. And Wikipedia will, too.
