I would submit to you that it is quite probable that the information for further learning is provided for people who do not need anything more said to know they “fit the bill”, and if you read the article and don’t know if you do, them you don’t—at least from the author’s perspective.

You might still enjoy learning more about it but you aren’t the audience the author is promoting it to.
