Nothing says user friendly like making the user read the manual for his manual so he can memorize the nine different categories (plus perhaps custom categores like TCLs) to get the manual page he wants.

I use man and apropos all of the time, but I have no illusion that they're new user friendly. They're amazing when you just need to look up some options or get the syntax for a system call, but if you've not assimilated the Unix way of thinking they're quite obtuse.
