This encapsulates one of my biggest gripes with Linux. A lack of appreciation for adequate/good documentation.

Making sure your users know how your program works, how to use it and what it's capable of seems incredibly important and useful to me.

If it weren't for Arch Linux's fantastic focus on documenting everything to do with Linux, I wouldn't be using Linux at all.
