"Writing on the Wall: Social Media — The First 2,000 Years' was published on October 10th in Britain and Commonwealth countries, and on October 15th in the United States. (To buy the book, click the links on the right.) I'm on the road promoting it for two weeks, starting in Seattle and ending up in New York. I talked about the book at Town Hall Seattle and at Powell's in Portland, and next week I'm speaking at Harvard (see above) at 7pm on October 21st and at Barnes & Noble Tribeca at 6pm on October 23rd. But mostly I've been doing radio interviews (and some TV) and visiting tech firms, including Twitter, Facebook and Google, to spread the word that what they are doing is not as new as they might think. To be fair, Dick Costolo of Twitter, who I saw while at Twitter HQ, has compared Twitter with the agora or marketplace of ancient Greek city-states, so he's been thinking along similar lines. So far the book has been reviewed by publications including the Guardian, Wall Street JournalIndependentFinancial Times and Literary Review. Having started work on this book in late 2010, I'm thrilled that it's finally available on bookshelves, both physical and digital, and that people seem to be enjoying it — and agreeing with my contention that, as the Wall Street Journal puts it, "what we tend to regard as the radiant novelty of the digital age may really be a rebirth".


The video of my TEDxOxbridge talk on “lessons from ancient social media”, based on my forthcoming book “Writing on the Wall” is finally available! I’m quite pleased with it, even if they did cut out my bad joke at the beginning (“Good morning everyone — It’s great to be here in the historic city of, er, Oxbridge.”) Anyway, the talk gives a good flavour of the book, with three examples of ancient social media environments (Romans, Luther, coffeehouses) and three lessons from history that we can apply today. The book, of course, contains lots more examples and concludes with many more lessons.

I would really like to do a longer, geekier version of this talk at SXSWi next March, under the title “Tweet like a Roman: Social media’s long history”. If that’s something you’d like to see, please vote for my proposal on the SXSWi site. Fingers crossed! Finally, the “Share it like Cicero” winners have been picked and notified, and the galleys are going in the post this week.

Having built PumpkinBot last year, Ella and I have just completed another Arduino-powered creation for her Latin homework. She wrote a long essay on the Oracle of Delphi, and to accompany it we decided to build our own version, called OracleBot. You shout your question into a microphone at the top, and it then replies using one of nine canned replies that are, supposedly, actual replies given by the oracle. And they really are canned replies: the whole thing is mounted in a Pringles tin. Here’s what’s going on inside:

Essentially it’s a very similar set-up to PumpkinBot, only with a sound sensor instead of a motion sensor, and a little amplifier board so we don’t need to rely on the Jambox for sound playback. That means we can fit the whole thing into the Pringles tin, powered by a USB battery. Ella recorded the sayings of the oracle herself, and we messed her voice around a bit using various apps. The software measures the ambient noise level when OracleBot powers up, and then looks for a deviation from that noise level that lasts more than a couple of seconds before playing back one of its replies (“Pray to the winds”, “With silver spears you may conquer the world”, etc). Because the oracle’s answers were always ambiguous, you can read a lot into its responses, and even have silly conversations with it. We’ve had a lot of fun building it over the past few weeks, and we hope her teachers like it!

Together with my daughter Ella I’ve been working on a special project for Halloween, which we call PumpkinBot. We have just installed it on the front porch to amuse (or terrify) visiting children as they come trick-or-treating. This is what it looked like when we finished it this afternoon (above). There’s a box of electronics and, of course, a pumpkin, for which Ella chose an “Eye of Horus” design. (She actually wanted a giant Lord Vaati from Zelda eye, but we couldn’t find a suitable version of it online, and decided this was just as good.) Here’s what’s inside the box:

The whole thing is powered by an Arduino Uno board, which is essentially a tiny computer. We fitted it with an MP3 playback shield so it can play audio, and plugged that into a Jambox speaker/amplifier so it’s nice and loud. We loaded a selection of spooky sound files (including some from “Portal”) onto a micro-SD card that slots into the shield. Playback of sound files is triggered by the motion sensor at the front of the box. At the same time, we switch on two high-power LEDs, which are on long wires so we can put them inside the pumpkin. Ella’s friend Georgia brought her pumpkin round, with a Mockingjay design from “The Hunger Games”, so we ended up putting an LED into each pumpkin. When someone comes up the path, they hear a spooky sound, and the pumpkins light up like this. Behold, the PumpkinBot!

The wheels are turning on my new book. “How Luther went viral” is an article I wrote for the Christmas issue of The Economist, extracted from one of the book’s early chapters, on the use of social media by Martin Luther. It was very heartening to see such a positive reaction to the piece on Facebook and Twitter, and I’m amused that people are still tweeting about it now, three months later. I also did a podcast to accompany the piece in which I examine the parallels with the Arab Spring, and the reaction of large companies to social-media criticism, in more detail. I took January off to work on the book, and I’ve now reached the 17th century, John Milton and Areopagitica. Writing about the Facebook of the Tudor court was fun. But I seem to be short of examples of ancient social media from Asia or the Arab world. Tipao? Dazibao? Any suggestions would be most welcome!

The wait is finally over, and we have the details about Apple’s tablet computer, the iPad. (It’s not such a great name, but that was what people thought about the iPod, so I expect we’ll get used to it.) We put it on the cover of The Economist this week, with a cover leader, which I wrote. This post is the longer, geekier version of my analysis of the iPad. The new device is essentially a giant iPod touch with a 10-inch screen and a very fast but power-efficient chip designed by Apple. It has super-sized versions of the iPod/iPhone apps, with more elaborate pop-up menus. It runs existing iPod/iPhone apps, which can be expanded to fill the whole screen; it also runs new apps designed especially for its larger screen. There’s a Wi-Fi version and a version with both Wi-Fi and 3G connectivity. (In America, there’s a special deal with AT&T allowing unlimited 3G access for $30 a month.) There’s an e-reader app called iBooks, backed up by an Apple e-book store called iBookstore. There are also new, touch-driven iPad versions of the apps in Apple’s iWork productivity suite: Pages, Numbers and Keynote.

What isn’t there? There’s no camera, but that’s not really a surprise; taking pictures with a device this big would be unwieldy. Instead, there’s an optional adapter to allow photos from digital cameras to be uploaded into it. Very handy if you want to post to Facebook while on holiday. Nor is there a forward-facing camera to enable videoconferencing. There’s no phone function. But there is a built-in mic, and I expect the iPad will work with the iPhone’s headphones, which also have a mic. It would then be possible to make calls using a VoIP app over either Wi-Fi or 3G. (Apple has just said that it will approve apps that do VoIP over 3G, something it would not allow before.) The ability to run multiple apps at once, which had been expected, is also absent. I think that will be added in due course, and to the iPhone too, much as copy and paste were last year. (A four-finger swipe might allow switching between full-screen apps, for example, like on the old Mac MultiFinder.) Some people were a bit disappointed by all this, but future software updates and hardware versions may fill in many of these holes, just as 3G was added to the iPhone a year after launch. And any disappointment ought to be tempered by the iPad’s price: it starts at $499, much less than anticipated. I expected it to cost $699 when I originally wrote my leader, based on my best guesses, on Monday afternoon. Read More
