  17. interest

  18. task (bug) #1 task (bug) #2

  19. task (bug) #1 task (bug) #2

  20. does it work? field study of developer productivity percentage change in edit ratio

  21. does it work? downloaded 2 million times per monthused by hundreds of thousands daily

  22. right information right time right place right way right person
