I'm not sure that's really limited to any of the BSDs, honestly. Newer Unices and Linux in particular are pretty darn user friendly relative to how it used to be. And users have the backstop of googling for any answer these days.

OpenBSD hearkens to the older school of thought that reading the docs is not a bad thing and in fact can be a great place to start. It reminds me of my start on UNIX puzzling out the mysteries of UNIX one man page at a time.

You are in a maze of twisty little man pages, all alike.
