Interesting interview with Slate editor – especially:
DIA: Do you feel people write differently for the web than they do for print?
Mr Weisberg: If they don't, they don't succeed online. Writing that's native to the web is different in ways that are crucial but subtle enough that you can miss them if you conceive of your audience as reading a printed product. The tone of good web writing grows out of email. It's more direct, personal, colloquial, urgent, witty, efficient. It doesn't waste your time. It reflects that engagement, responsiveness and haste of web surfers, as opposed to the more general passivity of print readers. It integrates the use of links into the creative and intellectual process as opposed to tacking them on afterwards. And it uses multimedia in an organic rather than an ornamental way.
