Author Nicholas Carr wrote a controversial post recently about the use of hyperlinks in online content, in which he argued that , and were likely to lead to less comprehension rather than more. This idea was an offshoot of Carr’s latest book, The Shallows, which makes the claim that the Internet — and digital media in general — are making society . Now Scott Rosenberg, one of the founders of the online magazine Salon and of a new media-accuracy startup called MediaBugs, has written an admirable series of posts defending the link . In his original post, Carr described links as “conveniences,” but said they also functioned as a distraction for readers:

Sometimes, they’re big distractions – we click on a link, then another, then another, and pretty soon we’ve forgotten what we’d started out to do or to read,” he wrote. “Other times, they’re tiny distractions, little textual gnats buzzing around your head.

The author said that research he looked at for his book showed this created a “cognitive load” for readers, and those who read hypertext “comprehend and learn less… than those who read the same material in printed form.” Some prominent writers and media figures agreed with Carr’s take, including — ironically — Laura Miller, a writer and book reviewer with Salon, who argued that links of synthesizing the topic properly, and said that most people don’t click on links anyway. Carr also got some support from Jason Fry, writing at , and Ryan Chittum in the Columbia Journalism Review (in the spirit of full disclosure, I on my personal blog).

As Rosenberg describes , much of the research that the author relies on for his attack on hyperlinks and comprehension don’t really fit with his broad thesis. For example, the kinds of links that were studied in the research Carr uses in “The Shallows” had nothing to do with adding context to the text that they were embedded in; in other words, they weren’t the kind of hyperlinks that everyone is used to in blog posts and other Internet content. As Rosenberg notes:

All this study proved was something we already knew: that badly executed hypertext can indeed ruin the process of reading. So, of course, can badly executed narrative structure, or grammar, or punctuation.

Instead of impeding understanding, as Carr and his supporters argue, Rosenberg says he believes that they deepen it, quoting author Steven Johnson as saying that links are a tool for synthesis, “a way of drawing connections between things,” to bring coherence to the vast universe of information online. “The Web’s links don’t make it a vast wasteland or a murky shallows,” Rosenberg says, “they organize and enrich it.” I’m firmly on the Salon founder’s side in this one — without links, what point is there in having hypertext at all? The whole idea behind Tim Berners-Lee’s invention was to enable sites to point to each other and create a “web” of context. Do they impose a cognitive load of some kind on users? Possibly, but in my view, the benefits far outweigh the disadvantages.

In , Rosenberg first takes on what he calls “corporate linking,” which is the practice of clogging up text with links “because they provide some tangible business value to the linker: they cookie a user for an affiliate program, or boost a target page’s Google rank, or aim to increase a site’s “stickiness” by getting the reader to click through to another page.” Rosenberg also argues that much of this is Google’s responsibility, because of the value attached to page rank and links:

Google is a great tool because it draws meaning from links. And it is a profitable company because it has placed a tiny but real financial value on many links. But by making links a business, Google also made it harder for editors and writers to defend responsible linking.

In the third , Rosenberg says that even if Carr is right and links do slow down reading and get in the way of understanding the content they appear in, he would still prefer to have links, because they are “additive and creative.” Links pull together different pieces of a topic and connect them into a whole, he says, and at their best, they also “show a writer’s work” and are “badges of honesty, inviting readers to check that work.” Rosenberg adds that the use of links has multiple benefits, including:

• Saying hello. “A link to another site can serve as a way of telling that site, ‘I just said something about you.’ This kind of link remains a valid and valuable social gesture.”
• Showing your work. “Some people are happier with this stuff collected at the end, as we did for centuries in print. But linking in situ gives the reader the information right where it’s needed.”
• Fairness. “Does a writer present the perspectives of those he disagrees with in a way that they feel is fair? Linking to those perspectives is a way for a writer to say: Go ahead — see if I got you right.”
• Adding context. “A fragment that gets connected is no longer a fragment. It becomes a working part, a piece of a mosaic, a strand in a web.”

As Rosenberg puts it in the conclusion to his series, writing online without linking “is like making a movie without cutting. Sure, it can be done; there might even be a few situations where it makes sense. But most of the time, it’s just head-scratchingly self-limiting. To choose not to link is to abandon the medium’s most powerful tool — the thing that makes the Web a web.” Hear, hear.
