The Guardian's Deborah Orr is probably right that the Marks and Spencer "shwopping" initiative is "an ugly word for a dubious enterprise", but I am rather taken with this promotion for the program. M&S is encouraging shoppers to "shwop" -- swap their old clothes for discount vouchers when they buy new clothes at M&S, with the old clothes going to charity -- and to promote the affair, they covered this large Truman Brewery warehouse building off Brick Lane with used clothes, to great effect.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
