It's hard to imagine a time without Facebook, but believe me, it existed - I was there. It was a time when everyone strived to have smaller mobile phones and Saddam Hussein was still hiding in a bunker clutching a bag of Funsize Mars Bars and a copy of Nuts Magazine.

When it comes to Facebook, we are still trying to figure out two things: what it is worth to us, and how much it should cost.

Despite my complaints, I remain optimistic about Android. Problems aside, diversity and openness breed innovation and, over time, I expect there to emerge a more harmonious Android ecosystem. But I got tired of waiting, which is why I bought that iPhone 4S.

I believe that one of the main reasons for the shortage of women in IT is due to the lack of female role models in the industry - what if Steve Jobs had been a woman?

The crucial point is that simply learning about internet safety is not enough, children need to practise it. With the right nurturing, guidance and practice, children can then have the best possible preparation when the time comes to make the transition into more grown up social networks such as Facebook and Twitter.

I am a reader and a Kindle owner, I have seen the demise of music and book shops on the high street. Going digital is not the answer W is looking for. The nature of the Singularity, of any Singularity results in the eventual destruction of historical preservation of the former.

Last night I was a the launch of Covetique... A new online space for buying and selling designer gear. Think of it as Net-A-Porter for the sensible among us.

With press days for this coming season drawing to close it has been interesting to see the effects that social media developments have had on the fashion industry. Acting like an expose on what is going on behind the scenes, social media sites, especially Twitter and Instagram, have allowed everyone to feel like they have had the chance to see what is going on.

Now that the huge hype created over the Facebook IPO has given way to more practical and analytical thinking, it is time to take a closer look at the tech IPO scenario.

It might seem hard to believe but the mobile phone was first introduced to the UK in 1985. Just 27 years later and the device that we now love is hardly recognisable to those first Motorola handsets. And it's not just the size and battery life that's changed.

While the West has been trying to develop the right platforms and technology for mobile payments to work, and technology providers and operators have been battling for mobile payment supremacy, Kenya has gone straight from a barter/gift/debt economy to digital transaction - leapfrogging over the last 100 years of the West's progress in monetary transactions.

And one of the key questions is how Facebook will increase the amount of revenue they earn from advertising and other services. Which leads me to a little experiment they have been undertaking recently in New Zealand.

String physicists assume that energetic pieces of threads are the keys to quantum gravity and to everything else of our perceived reality throughout the universe. The basic elements of this theory are "strings" or membranes, i.e. subatomic one-dimensional energy threads and built areas.
