Several answers at the link (which is via Metafilter), but this one got me:
Nicholas Carr, author of The Shallows: “The ‘device’ that feels most outdated to me is my blog,” says Carr. “When I started the thing, in 2005, the personal blog was the iconic expression of ‘new media’; having one put you in the oxymoronic category of journalist-hipster. But the action has moved away from blogs, to the more conversational social networks like Twitter and their bite-sized bulletins. To be a blogger today makes you feel a little like Norma Desmond after silent movies were replaced by talkies: ‘I'm still big; it's the internet that got small!’”He forgot to answer the question Why haven't you upgraded?
And, I will note, that he wrote a book. I thought the idea was most outdated. But then, the oldest thing you use might not be outdated at all. What very old technology do you use that you wouldn't disparage by calling outdated? What makes something "outdated"? Carr refers to where the "action" is. (I don't know that I care about that since I am old enough to remember the TV show "Where the Action Is.")
