It’s Back to the Future time, folks. This intriguing story from the Guardian

Sky News has told its journalists not to repost information from any Twitter users who are not an employee of the broadcaster.

An email to staff on Tuesday laid out new social media guidelines for Sky News employees, including a contentious ban on retweeting rival “journalists or people on Twitter”.

The new guidelines also warn Sky News journalists to “stick to your own beat” and not to tweet about non-work subjects from their professional accounts.

So much for the link economy, then. But the Digger’s (surprisingly entertaining) Twitterstream will, presumably, be exempt from the ban.
