"what motivates users?" What motivates me is creating books which are posted for other people read. If other people don't want to read it, then I am wasting my time. If other people would read it, but it never gets posted, then I am wasting my time. If I work on other people's projects, but those projects never get finished then I am wasting my time. If a bunch of self-appointed "high priests" [of technology] stand between me a getting something done, this demotivates me. If I can do it faster myself, I will. Good tools -- or at least not horrible tools -- motivate me. Bad tools -- tools that waste more of my time than tools I can pick up just about anywhere on the internet -- such tools demotivate me. New technology motivates me. Another thing that motivates me is spending $15 for a current generation book for my Kindle from Amazon and while reading it happily finding many times the amount of errors in it than would be tolerated by either DP or PG. And realizing books written today are not necessarily any better written than books written in the past. Old technology and being forced to follow standards abandoned as a mistake by the mainstream computer industry by about 1980 demotivates me. ----- For reference, I have two books still stuck in DP each of which has by now cost me many times the effort of doing the book entirely on my own. There are another 66 books I have helped work on at DP which have not been posted, some of which are about three years old. Stated in its simplest terms: DP is very good at starting books. DP is not very good at finishing books. The tools are not good. And volunteers' time and effort is not respected.
