I wish I could upvote this 10,000 times. Documentation isn't sexy or something. I don't know why Linux documentation sucks so much, but Redhat makes it suck must less. It takes lots of effort, money and writer hours to create the kind of documentation that Redhat maintains and businesses love documentation. A HOWTO or a FAQ are not documentation. I actually prefer man pages and I dropped Linux for my personal project…
Well, part of the reason Linux documentation often isn't very good is that Red Hat doesn't treat documentation work as something that should be submitted upstream. Their incentives favour creating Red-Hat-specific documentation, and this then reduces their users' incentive to improve upstream documentation.
Red Hat has contributed work that made distros more homogeneous (cough systemd cough) and excellent package documentation for that work; but also got flak for that...
