And remember, anyone is welcome to contribute in documentation ;) For the "ICT" people it's "show me the code", and for the rest it's "show me the money" or "show me the words"...errr..and some other things...among others.
The thing is, most of those who come to Free Software from a commercial environment have difficulty adapting to the culture. The lack of documentation is exactly the result of that fact (not being aware that you can contribute in many ways and the community thing isn't a joke at all).
