It seems unlikely that the founding fathers of social media had in mind a revolution of any greater magnitude than turning your teenager’s bedroom walls inside out and making themselves rich in the process. Still, here we are, less than a decade later, reeling from a series of very literal revolutions which have, over the past nine months, upheaved a vast tract of the Arab world and recalibrated the definition of people power. Revolutions which, the BBC now claims, were catalysed and facilitated by Facebook.

In films featuring computer whizzes, there is always a key scene in which, to illustrate the whizziness, a star actor bashes on a keyboard at implausible warp speed. The Social Network is the first major film to respond to the drama inherent in the internet boom. (What’s next? Google in China: the movie? Tehran: the Twitter Revolution?) But it’s one of The Social Network's unremarked attractions that a movie starring computers has no truck with fetishising geekery.

@Wossy seems to have been cast as second baddie in #PiratesduCaribbean 4

This intro is entirely about namechecking the films so they can cut away to the US stars who've jetted in from #Tinseltown

Lame string of Little Fockers jokes.

These clips montages always make films look like the complete Shakespeare. Then you go and see them...

With its finger-on-the-pulse tagline, “Welcome to the anti-social network” and respectable credentials, Chatroom is an intriguing prospect. It’s based on an acclaimed stage play, directed by the visionary Hideo Nakata (Ringu, Dark Water), with a script by Enda Walsh (Hunger) and populated by a cast of bright young things including Aaron Johnson and Imogen Poots. However, this cyber-thriller offers precious few thrills and is hampered cringingly by an absolute lack of authenticity. It is, as its title and tagline suggest, an exploration of the chatroom phenomenon, focusing on five teenagers as they forge friendships in cyberspace; yet it is so hopelessly out of touch with the generation it purports to portray that, although the overarching premise rings (fairly) true, it is for the most part excruciatingly inaccurate.

Ever since Catfish appeared in the States earlier in the year, debate has been raging about its bona fides. On the face of it an ingenious documentary playing smartly with the potential and pitfalls of social networking and the nature of personal identity in the cyber age, the film has triggered cries of “foul” from a number of critics and viewers. Morgan Spurlock, who made the junk-food odyssey Super Size Me, has called Catfish “the best fake documentary I’ve ever seen”.

Success has many parents, the old saying goes. And that’s certainly the case in David Fincher’s new film, an enthralling dissection of one of the great success stories of our age. When Harvard undergraduate Mark Zuckerberg devised a putative version of the Facebook website in October 2003, he can not have imagined it would spawn a global phenomenon with more than half a billion users. Nor could he have predicted it would result in a sea of litigation that would pit him and his company against both aggrieved former friends and slighted foes alike.

Part 2 @bbcproms. The madness begins. Ms Derham has not switched gowns in the interval. No sign of Titchmarsh, for which we must give thanks.

The "traditional" necklace of laurels for Sir Henry Wood's bust. Wonder if he'd welcome his head being polished by a pink rag.

How do they pick these pieces? Apols but the Marche joyeuse did not fill this tweeter with joy. On the other hand, here's Renée plus a mike.

JasperRees Not long now till Tony Blair faces interrogation by A Marr. GraemeAThomson and I tweeting a live review

GraemeAThomson Nice to see they’ve scheduled it straight after Restoration Roadshow. Someone at the Beeb with a GSOH?

GraemeAThomson Marr's gone with the orange tie. Provocative

JasperRees Are you prepared to speculate about the timing of the Hague twin-bed allegations? Who wins? Who loses?

JasperRees Not long now till @SweetingAdam and I start tweeting our live Friday Night @Wossy review here. 10.35 sharp.

SweetingAdam @JasperRees you could cut the atmosphere with a rolling pin

JasperRees I won't miss those bubbles. Or that music. It's sort of a bit rubbish

JasperRees BTW We are now reviewing Friday Night with Jonathan Ross, live on Twitter. He's said he's not going to cry

JasperRees Are you there, @SweetingAdam? I'm doing this on my tod. (My daughter: 'Are they all gay?' She's 17)

SweetingAdam Are the 4 Poofs employable in a post-Woss world?

JasperRees I believe they charge a mint for personal appearances. No doubt they're upping sticks for ITV1 too.
