From Patrick Kingsley’s article, “The Art of Slow Reading,” in The Guardian:
If you’re reading this article in print, chances are you’ll only get through half of what I’ve written. And if you’re reading this online, you might not even finish a fifth. At least, those are the two verdicts from a pair of recent research projects – respectively, the Poynter Institute’s Eyetrack survey, and analysis by Jakob Nielsen – which both suggest that many of us no longer have the concentration to read articles through to their conclusion.
And just in case the research proves predictive in your case,
What’s to be done, then? All the slow readers I spoke to realise that total rejection of the web is extremely unrealistic, but many felt that temporary isolation from technology was the answer. Tracy Seeley’s students, for example, have advocated turning their computer off for one day a week. But, given the pace at which most of us live, do we even have time? Garrard seems to think so: “I’m no luddite – I’m on my iPhone right now, having just checked my email – but I regularly carve out reading holidays in the middle of my week: four or five hours with the internet disconnected.”

I read with the ‘new mail’ ding turned off, and I limit my internet exposure, when discipline allows me. I find it helpful, though, to be able to read entire posts in my rss feed. Has someone tweaked with this blog so that it only sends the first few lines out that feed making a reader click through to see the whole? Who would do such a dastardly thing?
Someone conducting an unscientific experiment of sorts! :)
