My favourite book so far this century: Made to Stick.
How strange, then, it is that I've only just discovered that Chip and Dan heath have a page devoted to their fast company articles: http://www.madetostick.com/fastcompany/.
They've got a new book coming out next year, btw: http://www.amazon.co.uk/gp/product/1847940315/ref=s9_sima_gw_s1_p14_t1?pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=center-2&pf_rd_r=12SFY1C15FYAC0T5ZH1T&pf_rd_t=101&pf_rd_p=467128533&pf_rd_i=468294
