I am like someone stated above, it be a decision maker by itself...
However.. There is a long term effect for me. If you have bookmarks I am more then likely to atleast skim if not even read some of your PDF, which in turns means I will probably put some of it into my game in some form or fashion. Then lets say you release another PDF, this time I will look at it and think, I did find some useful items in his last piece of work rather then, I haven't even looked at what this publisher has in his last PDF.. why buy another?
