Sherlock and Doctor Who creator Steven Moffat: Don't tweet me!

The man who brought us Sherlock and Doctor Who reckons Twitter is the "worst" when it comes to understanding an audience.

Steven Moffat says he has no intention of tweeting again after quitting the social network three years ago. "I think Twitter is a useful tool for promoting a show, but I think it is the worst possible form of audience research," he told Comic-Con.

People "might be witty" or "might be clever" but "that is not a typical audience member talking," he explained.

"People on Twitter are having fun, they're making gags... it's like overhearing a pub conversation, when you're at a pub do you tell the truth, or do you try and get attention?"

Moffat, actor Rupert Graves, who plays Lestrade, and the show's executive producer, Sue Vertue, also revealed details about the planned 90-minute Sherlock special which will air later this year.

Moffat said: "The Sherlock special is set in Victorian times, so it's a different version of the show we're used to.

"It's like we checked the books and discovered we'd set it in the wrong time period by mistake and it's like we're correcting it for 90 minutes.

"We're really proud of it, we think it's a real cracker. But that'll be it until series four."

The fourth instalment of the show is due to return in 2017 and Moffat revealed they have not started writing it yet."
