This bit from a Financial Times piece, ostensibly about how social media is improving people’s writing skills, explains so much:
“Major Memory for Microblogs”, a recent article in the academic journal Memory & Cognition, found that people were much better at remembering casual writing like Facebook posts or forum comments than lines from books or journalism. One possible reason: “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.
Despite effort put in to erudition, it seems that even trollish comments are just, well, stickier. Not necessarily more convincing, mind you, but like a terrible fast food meal, that shit stays with you. Something to keep in mind, no?
