In my career as a journalist, I’ve written countless stories about many weird and wonderful things. Here are a handful to give you a flavour of my writing, my opinions and my expertise.

Note: While generally a fairly prolific writer during my time at the Guardian, I was quieter between 2002 and 2005, when I was working in editing - rather than writing - roles.

GENERAL INTEREST

Moving to California in 2008 allowed me to broaden my repertoire beyond the technology industry and write about some major news incidents.

In August 2009 I wrote a selection of pieces on the 18-year ordeal faced by kidnap victim Jaycee Lee Dugard - best read together.
• Police focus on spate of unsolved killings
• A world of nightmare: Jaycee Lee Dugard’s story
• Antioch: scene of chaos in a place where few questions are asked

• I’m not the messiah, says food activist – but his many worshippers do not believe him, March 2010
Members of religious group believe London-born author has come to save the world

INTERVIEWS

I’ve met nearly everybody worth meeting in the technology business, from industry luminaries and startup entrepreneurs who went on to make millions all the way down to the people doing the hard work at the coalface. Here are some of my favourites.

• The coolest player in town, September 2005
Apple’s chief executive Steve Jobs, the man behind the iPod phenomenon, gives an exclusive interview to Bobbie Johnson about his drive to make technology simple

• Inside Twitter HQ, July 2009
Twitter is the hottest internet startup on the planet. Over the last few months, the messaging service it provides has morphed from a social networking tool into an instrument of revolution. So what’s life like for the 52 employees at its San Francisco headquarters?

• Stars in your lap, February 2008
They crack open a beer, they joke, they spoof, they dissect the news - and they’re just a few keystrokes away. Can the new wave of cyber celebrities break out of the techie realm and into the bigtime?

ISSUES AND INVESTIGATION

A lot of technology writing focuses on personalities, gadgets and company conflict. But the problems that go on behind the scenes are often far more important and run much deeper. Over the years I’ve looked behind the scenes and discovered some amazing and terrifying things - with reporting that, in some cases, has had a major impact and led to genuine change.

• ‘No one is ready for this’, April 2009
A few years ago, the idea of hackers bringing the world to the brink of catastrophe was just a fun Hollywood plotline. Now, cyber-attacks are on the rise and Nato’s top computer experts have gathered in a military base in Estonia to prepare cyberwar defences

• Security flaw leaves 3m HSBC online accounts open to fraud, August 2006
One of Britain’s biggest high street banks has left millions of online bank accounts exposed to potential fraud because of a glaring security loophole.

• Situation critical, May 2007
The BBC’s desperate attempt to lead the new media revolution has been fraught with controversy, delays and huge costs. How did it all go wrong?

I wrote a series of pieces attempting to untangle some about the energy footprint of the internet. They proved important markers in a vital conversation.
• Web providers must limit internet’s carbon footprint, say experts
• Google’s power-hungry data centres
• The net’s hunger for power: Google responds

ONLINE CULTURE

One of my favourite areas to explore is the intersection between internet culture and the rest of society. The two have become much closer over the years, but the gap between them has produced some really interesting stories.

• The short life of Kaycee Nicole, May 2001
For two years, a young American girl recounted her brave struggle against leukaemia in a daily online diary and drew thousands of supporters. But when she died, it turned out there was just one problem…. she’d never existed.

• How three Swedish geeks became Hollywood’s Number One enemy, August 2007
As the internet’s number one destination for illegal downloads, the Pirate Bay has raised the hackles of the entertainment industry and elevated its founders to the top of Hollywood’s most wanted list.

• Meme genies and a meeting of minds
The internet ‘microcelebrity’ conference ROFLCon in Boston ponders bad dancing and sneezing pandas.

MULTIMEDIA

The Guardian has rightly developed a reputation for multimedia reporting, and I’m proud to say that I helped pioneer a number of multimedia reporting projects and features while I was there.

• Tech Weekly podcast
The word ‘podcast’ was actually coined in the Guardian’s technology section back in 2004, but we didn’t jump on the bandwagon straight away. I started off helping launch the Guardian’s Science Weekly podcast, but in 2007 we decided it was time for a technology-specific show. Hosted by Aleks Krotoski, it now gets tens of thousands of listeners each week.

• 30 seconds that changed the world, January 2009
Working with a colleague to produce a package marking a quarter of a century of the Macintosh computer, I conducted interviews with Apple co-founder Steve Wozniak and engineer Andy Hertzfeld. It turned into a great little multimedia feature, crossing print, web, video and audio.
