Simon Kuper of the Financial Times examines the impact of social media on writing:
“The relatively unfiltered and spontaneous production of one person’s mind is just the sort of thing that is readily stored in another’s mind.” That’s probably why Twitter, Facebook and reality TV are successful.
More people are writing because of the rapid communication of social media, and they’re doing it in an organic, conversational prose which is how we’re instructed to write in the first place.
We may waste time on social media but at least our brains are forced to think through participation. This is much better than passively watching TV and letting the neurons go to sleep.
