I have just realized that I like the user-made stories on Kanji Koohii more than the RTK stories (I also own the book).
The only thing that makes me stop using Koohii stories, is the absance of primitives on user-made stories. Even though that I like the user-made stories more, I have the impression that RTK stories are designed (throughoutly planned) with the primitives to make the learning easier on more complicated kanjis at further stages of the book.
Am I wrong? I will be glad to hear that I am wrong because I find the user-made stories more simple and easy to remember and usually more fun.
In other words, I fear that I will have difficulty at further stages if I start learning with user-made stories.

What do you mean? A lot of the early kanji has bad stories (for example "one") because people are new to RTK.
But in general stories shared on Koohii mention primitives, or some other custom primitive like "Mr T".
Not everyone uses formatting however. Primitives should be enclosed with * stars * (italic formatting).
When I check RTK1, the first stage of the book teaches about primitves along with the Kanji. However, the user-made stories do not teach about primitives. That's why I had the impressions that primitives are not used in user-made stories (because they are not introduced at the early stage of user-made stories like RTK1 does, right?).
If primitives are used, then I am wrong with my assumption. However, I wonder how people learn about the primitives without the introduction of them in Koohii. Am I missing something Fabrice?
It makes sense to use the site alongside the book. For each group of kanji with a new primitive, I would suggest seeing what the book says first, and then checking Koohii for stories. That way, you learn about the new primitive from the book, and can then pick your favourite story from Koohii.
The stories in the book stop part-way through, and the Koohii stories become more important at that point.
Some Koohii stories use the same primitive meaning as in the book, and some change it to a custom primitive meaning (which the story's author found easier to make memorable stories with). Sometimes, a custom meaning catches on (like using "Mr T" for "person") and lots of people post stories using that meaning.
You can name a primitive anything you want, and this shouldn't cause any problems later, as long as the new meaning doesn't clash with any other primitive meaning that appears later. If you pick a primitive meaning that's not very popular, then you might find there are no Koohii stories with your chosen primitive meaning for later kanji with that primitive, and need to make your own stories for those kanji. But this is not a major problem, and sometimes it's worth it.
If you look through the Koohii stories for the first kanji in which a new primitive appears, you can usually find an explanation of where people have changed the primitive's meaning.

Actually interestingly there's quite a few user created primitives in later kanji. They're quite useful. Unfortunately, yes, this site does not introduce the primitives individually like Heisig. I think that would potentially move this site over the line for copyright though, as many are distinctly Heisig's creation.
Sure a large portion of the "primitives" are radicals.
However Heisig also tried to bring method to madness. His term "primitives" references one or more radicals, together. So he create blocks out of smaller blocks, to help remember characters. So that you don't have to make a mnemonic with 10 keywords in it. Instead you have 3 keywords, one of which itself you memorized earlier.
