Yes, I certainly do. Unfortunately, it seems that many if not most of the help documentation out there is written hastily, as an afterthought, and not tested. Programmers like to write code, not documentation- at least, so it’s frequently been said both on various blogs and on the maillists I frequent. This is a problem, because they also frequently don’t like to write readable code. In a few cases I’ve looked at the codebase of a project with a view to improving it’s documentation, only to find myself lost in the code. I’ve not found any tactful way to bring this up without the developers having a snit about it, either.
