The Lightroom community help system has just gone public. Adobe's not the first software vendor to use Wiki technology to get customers to write the product manual that you used to expect the developer to provide. It makes a whole lot of sense too - users often know much more about the real world issues and can be more brutally honest than the manual writer (or Lightroom author). Just as supermarkets transferred to customers the work of being served, packing bags, even scanning bar codes at the checkout, software manuals are so 20th century.
