Even sweet old Radio 4 is getting in on the act; last night I heard them encouraging people to use the hashtag #r4riot and join in with one of their live shows.

But my favourite example recently is Riz Ahmed, an actor in Four Lions, tweeting live (simultweeting?) along with a screening of the film on TV. What a great way to spread the word and encouraging re-watching. It’s a bit like the audio commentaries you get as extras on DVD, but much more vital.

It might be easy to dismiss Miso as derivative, but I think it’s got a good chance of catching on (I’ve talked about Real-time watercooler moments and social tv before).

Whereas “Bob just checked in to North Acton station” is so what, “Bob just watched Madmen episode 4×10 can elicit real interest for a conversation – “Ooh what did you think of the bit where…?”

I suspect we’ll see a slew of other non-location check ins – sports games? fashions? video games? books? I can imagine “Dave just checked into The Girl Who Kicked the Hornet’s Nest” being a basis for a conversation.

One of my favourite NPD tricks is Break One Rule – take a successful formula and change one thing. I think Miso does this well.

Ahead of the filming of the fourth series of the IT Crowd, he’s asked fans to help dress the set

…send us your poor huddled zines, your artwork, your comics, your T-shirts, your memes. Anything you think should be in there that we might have missed

Not only is this financially sensible, but it’s also a great way of engaging fans, giving them a deeper sense of ownership and a real reason to spread the word about the new series.
