I was actually in the early stages of writing a post about this same subject — that, contrary to what intelligent people like Jonathan Franzen and Tyler Brûlé have been saying or implying about Twitter (which they don’t use, and therefore don’t really know), it’s often not a replacement for reading, say, long-form journalism or high-quality fiction. It’s an enabler of it. I have those I follow on Twitter to thank for many meaty essays and recommended books I’ve now taken in. It was on Twitter where I learned about (and then supported on Kickstarter) Distance, a new quarterly journal with "long essays about design.“ And it’s where I learned of Offscreen, "a new periodical with an in-depth look at the life and work of digital creators — captured in enduring print.” Neither of those two new long-form publications, efforts Brûlé would surely champion, would exist without Twitter as the network that brought its contributors, investors, and readers together.
So, as I was saying, I was going to write a post about all this. But then The New Yorker’s Sasha Frere-Jones wrote one, and his is sharper than mine would have been. I recommend you read it. And, if so inclined, share it on your social network of choice.
