What the Internet is doing to our brains / NICHOLAS CARR


For more than a decade now, I’ve been spending a lot of time online, searching and surfing and sometimes adding to the great databases of the Internet. The Web has been a godsend to me as a writer. Research that once required days in the stacks or periodical rooms of libraries can now be done in minutes. A few Google searches, some quick clicks on hyperlinks, and I’ve got the telltale fact or pithy quote I was after. Even when I’m not working, I’m as likely as not to be foraging in the Web’s info-thickets’reading and writing e-mails, scanning headlines and blog posts, watching videos and listening to podcasts, or just tripping from link to link to link. (Unlike footnotes, to which they’re sometimes likened, hyperlinks don’t merely point to related works; they propel you toward them.)
For me, as for others, the Net is becoming a universal medium, the conduit for most of the information that flows through my eyes and ears and into my mind. The advantages of having immediate access to such an incredibly rich store of information are many, and they’ve been widely described and duly applauded. “The perfect recall of silicon memory,” Wired’s Clive Thompson has written, “can be an enormous boon to thinking.” But that boon comes at a price. As the media theorist Marshall McLuhan pointed out in the 1960s, media are not just passive channels of information. They supply the stuff of thought, but they also shape the process of thought. And what the Net seems to be doing is chipping away my capacity for concentration and contemplation. My mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles. Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski.

PageRank algorithm / Wiki

PageRank is a link analysis algorithm, named after Larry Page and used by the Google Internet search engine, that assigns a numerical weighting to each element of ahyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is referred to as the PageRank of E and denoted by PR(E).

Why links matter: Linking is the lifeblood of the web / Mathew Ingram

Many online media outlets continue to rewrite news without providing a link to the original source, but doing this is both rude and short-sighted: Linking is one of the fundamental underpinnings of the internet and a crucial part of the culture of the web.

Every so often, a controversy erupts over something that seems relatively simple: Namely, the concept of linking to (and thereby giving credit to) the source of a news report. In one of the most recent examples, Instapaper founder Marco Arment — who broke the news about a wave of corrupted apps in the Apple store — kept track of both media outlets that repeated the news and whether they gave credit to him or not. Some did but others didn’t, and some hid their links or otherwise tried to make it look like they broke the news themselves. There are a number of reasons why this kind of behavior is still so common a decade after digital media became mainstream, but none of them justify it. Simply put, linking is a core value of the web, and if we lose that then we have lost something incredibly important.
