Image of the week: Twitter's got talent
Britain's Got Talent shadow theatre group Attraction, of YouTube sensation fame (look it up), has decided that for its next routine, it's going to re-enact the drama that is the Twitter initial public offering. Well, that's what we thought when we saw these random smartphone owners silhouetted against Twitter blue. At the time of writing there has been comparatively less drama about the Twitter flotation than there was for Facebook's debacle of a debut on Nasdaq. Nevertheless, in an ideal world, all major business stories would be reinterpreted through the medium of dance. Photograph: Kacper Pempel/Reuters/Files

The lexicon: wardrobing
One in six women in the UK admit to "wardrobing", which is that time-honoured practice of buying clothes, wearing them and then taking them back for a refund, according to a survey by Voucher Codes.co.uk. Job interviews, weddings and black-tie events are the occasions where women are most likely to shuffle back to the shop muttering something about the wrong size, though frankly if you're harbouring the intention to return a dress after a night out, you're already limiting your potential for fun. In the US, they call this money-saving habit "return fraud", but "wardrobing" sounds much nicer.

Getting to know: Alan Mulally
Ford chief executive Alan Mulally is apparently the second-favourite (behind former Nokia boss Stephen Elop) to be the next leader of Microsoft. Mulally (68), who has an engineering background, is credited with reversing losses at Ford and helping it avoid a federal bailout, and a turnaround expert may be precisely what Microsoft needs. Indeed, one reason Mulally has been tipped is that he reportedly advised departing chief executive Steve Ballmer on the tech giant's latest restructuring, known as One Microsoft. The carmaker's reinvention plan, meanwhile, is called One Ford. It may yet transpire that, for Microsoft, there is only One Alan.
