Feedback is king these days. Wherever you go online, the pressure is on to pass judgement: Was this site useful? How do you rate this article? Please take a minute to fill in our user experience survey. In the same vein, gamers are forever monitoring their progress on leader boards.

The hunger for feedback is also starting to reshape the workplace. Many younger employees now expect a running commentary on their performance. Not for them the old annual or semi-annual review: they want to know how you think they did in this morning’s presentation, and they want to know now. You can even buy special software to create a round-the-clock feedback loop for staff and clients.

Yet this begs an obvious question: Is being constantly ranked, rated and evaluated a good thing?

True, there is much to be said for knowing what your colleagues and boss think of your work and to hear this more often than once or twice a year. Input from a wide range of people can also enrich many decisions and projects a principle known as the “wisdom of crowds“.

But there are limits. Otherwise the wisdom of crowds can start to resemble groupthink.

We are social animals, after all, so we have a natural desire to fit in, to please our peers - to earn good feedback. Research into online behaviour suggests that other people’s opinions can narrow our horizons. When visiting a site where movies, books, etc are rated, users tend to click on the items with the highest rating first.

It’s like buying a song on iTunes: if there are multiple versions available, which do you listen to first? I know I always click on the one with the highest popularity ranking. I follow the herd, in other words.

This raises the possibility that too much feedback too fast can close down avenues of inquiry and pull us away from the fertile soil of serendipity.

It may also hamper our creativity. Some acts of creation are intensely private. You cannot orchestrate them by committee. A person has to sit alone with his doubts, fears, frustrations, dreams and demons untangling, parsing and processing these at his own pace.

Many creative triumphs have come from someone toiling away alone, free from the tyranny of other people’s judgements. James Joyce wrote Ulysses without a daily critique from his editors; Mozart composed his Requiem and piano sonatas without hourly feedback from his patrons; Picasso only unveiled his paintings to the world when they were finished.

Would these giants have produced the same imaginative breakthroughs, the same revolutions in thought, if they had worked with a constant drip-feed of other people’s feedback? I’m not so sure.

Surely the answer is to strike a balance. Feedback at the right speed: sometimes fast, sometimes slow and sometimes no feedback at all.

It goes without saying that any feedback on this post is more than welcome…

Ever since In Praise of Slow came out in 2004, readers have been urging me to publish a companion volume in the style of a how-to manual. I have always resisted. Writing a self-help book with tips, techniques and exercises is not really my thing.

But then last year I hit on a compromise. A wonderful multimedia company calledSounds Truesuggested I record an audio version of the self-help book that readers were asking for. A few months later, I found myself sitting in a studio in Boulder, Colorado, a gloriously slow town in the Rocky Mountains. It was an extraordinary experience. I spent two days in a studio, munching dried fruit, drinking industrial quantities of water and talking into a microphone. It was a chance to revisit old material, ideas and emotions - and to give them all a fresh twist. A real privilege.

The good news is that no one has to listen to me yakking on for two days. My heroic producer, Nancy Smith, has edited everything down to a very tight three hours (on three CD)s. She has also edited out the sound of my eating and drinking.

The final product iscalledThe Power of Slow.

If you pick one up, let me know what you think.

Talk about climate change. Britain is grappling with the largest snowfall in nearly 20 years. London is buried under seven inches of the white stuff - and there are still flurries blowing around outside my window. The country has ground to a halt. In London, there are nobuses, no Tube, no school, nothing.

This is a huge inconvenience for many, but there is also a silver lining. To begin with, children are over the moon to have the day off school. Mine dashed outside in just their pajamas and boots this morning before breakfast. My son declared it the “best day of his life.”

Many Londoners know how he feels. The absence of traffic has changed the whole mood and feel of the city. Streets normally clogged with cars and buses are now full of children (and adults) building snowmen, throwing snowballs and even tobogganing. Neighbours who usually avoid eye-contact are stopping to chat about the weather. This is hardly surprising:Studies around the world show a direct correlation between cars and community: the less traffic that flows through an area (and the more slowly it flows) the more social contact among the residents.

I do not mean to demonize cars. I drive one myself. The trouble is that driving has gained too much ascendancy over walking. For decades, urban life has been haunted by the words of Georges Pompidou, a former president of France: We must adapt the city to the car, and not the other way round.

How wrong can someone be? The city of the future - a truly Slow city - must take a different tack. It must adapt not to the car but to the citizen, to the pedestrian, to human beings. And it shouldn’t wait around for a snowstorm to do so.

By coincidence, this snowfall has hit Britain on the day that alandmark studyon the statechildhood hit the headlines. The report sounds fascinating and flawed, and I will blog on it later once I’ve actually read it. But a quick comment now.

On the BBC this morning, one of the report’s authors blamed the unhappiness of modern British children on career-obsessed parents, competitive schooling, broken families, excessive consumerism etc. But he failed to mention our collective reluctance to let them run around and play outside on their own. If we want happy, healthy kids, then we need to redesign and rethink our cities so that they have plenty of outdoor space for play. And surely reclaiming the streets from traffic must be a first step to achieving that.
