There are many lessons to come out of the phone-hacking trial, which concluded two weeks ago. One is the power of networks. The remarkable rise of Rebekah Brooks was fuelled not only by her qualities as a reporter and editor, but also by her symbiotic talent for building circles of support, drawing close the likes of David Cameron and Rupert Murdoch. There will always be insider groups, cabals of neighbourly millionaires who bond on horseback as they canter between their estates, but the way they are created has changed. A wider trend is happening, which has the potential to transform the way we do business and live our lives. Whereas Brooks’ networking was egotistical, power-hungry and self-centred, today it’s about softer skills: the exchange of ideas, mutual inspiration and, critically, helping others as much as helping yourself. The first rule of new networking is — you do NOT talk about networking.
