This morning’s Observer column.

For hardcore geeks, the WikiLeaks saga should serve as a stimulant to a new wave of innovation which will lead to a new generation of distributed, secure technologies (like the TOR networking system used by WikiLeaks) which will enable people to support movements and campaigns that are deemed subversive by authoritarian powers. A really good example of this kind of technological innovation was provided last week by Google engineers, who in a few days built a system that enabled protesters in Egypt to send tweets even though the internet in their country had been shut down. “Like many people”, they blogged, “we’ve been glued to the news unfolding in Egypt and thinking of what we can do to help people on the ground. Over the weekend we came up with the idea of a speak-to-tweet service – the ability for anyone to tweet using just a voice connection.”

They worked with a small team of engineers from Twitter and SayNow (a company Google recently acquired) to build the system. It provides three international phone numbers and anyone can tweet by leaving a voicemail. The tweets appear on twitter.com/speak2tweet.

What’s exciting about this kind of development is that it harnesses the same kind of irrepressible, irreverent, geeky originality that characterised the early years of the internet, before the web arrived and big corporations started to get a grip on it. Events in Egypt make one realise how badly this kind of innovation is needed.
