There are suprisingly few beginner tutorials for FreeBSD (or any BSD). Compare that with the gazillion tutorials for Linux. The official FreeBSD Handbook is rightly praised for it's thoroughness and its detail. But it is also a bit intimidating and dense for beginners who may need a simpler guided tour of the essentials.
Of course, there is a lot of cross-over knowledge between Linux and BSD. Nevertheless, the difference between the number of Linux guides, books, and courses and the number for BSD is striking.
There is just one book on FreeBSD published in 2018 (Absolute FreeBSD). But nothing else recently. What about BSD on Udemy, Pluralsight, LinkedIn Learning (Lynda)? Nothing. Why is there so little for an OS that is well-regarded and widely respected? (Not a criticism of the situation, merely an observation.)
