From Digital Spy's live blog:

Steven also reveals that he was surprised by how much fan expectation there was for Moriarty prior to the character's debut - they didn't realize that the general public knew about the villain.

And I thought he's the most well-known Sherlock Holmes villain. I mean, it was already said by Moffat and/or Gatiss: a fuckload of villains after him were pretty much a copy of Moriarty. Before Sherlock I had never read a Sherlock Holmes book or watched a movie, which makes me part of the general public, but I did know of Moriarty.

The Irish actor reveals that he looked at Twitter to see what people thought of his performance and read some "unforgettable" comments - some positive, some not. He compares the experience to being "kissed... then punched... then hugged..."

I wonder what some of those unforgettable comments were. Hugs and kisses from me! Argh, just one actual, real-life hug, please? *puppy dog eyes*

Discussing the controversy surround the Sherlock / Irene romance (or is it a romance?), Steven cheekily admits, "We knew giving Sherlock a girlfriend - sort of, kind of - would make certain people really cross!"

Fuck you. No, seriously. He's probably thinking of the Johnlock shippers there, but I'm not even a shipper and his swaying into sexual/romantic territory annoys me.

Moffat talks the popularity of the Molly Hooper character - "We never intended to introduce a character - especially as a regular - who wasn't in the original," he admits, adding that they were won over by Louise Brealey's initial scenes in 'A Study in Pink'.

Well, I'm glad we got to keep Molly! But we still don't know what exactly her job is. D:

Moffat admits that they didn't know that Sherlock would return when the series one finale was written, adding that it was "cheeky" to end on a cliffhanger. "Had we never come back, they'd still be at that pool."

If I could write, I'd start a fic now where Sherlock, John and Jim are stuck in pool limbo. They'd just keep doing the mostly same things, because after a few minutes they've forgotten that they've done it before, a million times.

Moffat and Gatiss both claim that they know how series two's cliffhanger will be resolved, and indeed knew when they shot the episode.

Well, one can only hope so - seeing as they already shot the resolution together with 2x03.

Andrew Scott refuses to confirm if he'll return as Moriarty in a third series - "Moriarty is dead," he mumbles - but admits that he knows how Sherlock survived too. Cheeky!

Was he there when they shot the resolution or was he told?
Pfft, over at Tumblr people are freaking out about the confirmation that Jim is dead (Although Moffat could have asked Andrew to lie - maybe he was mumbling because he was uncomfortable with lying?). Personally I don't see any reason to freak out, because 1. The whole time I've been convinced that Jim is dead. 2. His death doesn't impair my MorMor shipping (I didn't even ship them until after Jim died). 3. Just because he's dead doesn't mean he can't be in S3. I'm still hoping for flashbacks (and that Andrew knows how Sherlock survived points towards that).

And here's what we've been waiting for - the three words that describe the episodes of Sherlock series three - Rat, Wedding, Bow. That's RAT. WEDDING. BOW. What does it mean?! Get Googling!

Not Empty or House? Okay then. Wedding, hm... I think they said that John wouldn't get married. Maybe that was a lie? Personally I wouldn't mind if John got married, although that would probably mean that he'd move out of 221b, which makes a bit sad. Bow - he wears a bow tie now. Bow ties are cool :oP. No, but really, the pronunciation is like in His Last Bow. Incidentally I only just read that story. And things have changed so much by then, it makes me sad. On the other hand I guess this would work well as the evil season finale we were promised.

Does fan criticism on either of his shows annoy Steven Moffat? "I'm annoyed by any criticism," he quips. "I try to avoid a lot of the online stuff." Mark Gatiss adds, "It's the equivalent of listening at doors - don't listen at doors if you don't want to hear something bad about yourself."

Hey, I know that criticism isn't fun, but not all of it is bad! Some of it gives you pointers on where you could improve!
