OP, all that is needed for beginners is reading. If people can read, they will find sections of interest to them. They don't need to be directed somewhere based on your visions on the forum, just because the forum is multifaceted and everyone has different questions.
But I want to say that you, OP, are confusing the purpose of the forum. This is a forum about Bitcoin, first and foremost. After all, about crypto. For many newcomers, visiting the “politics” topic exists only to accumulate the required number of posts to increase their activity. You can also watch how some of the local sections that people were so passionate about also turn into discussions about their own country, which is basically a far cry from the discussion on the forum. And in turn, it is this section, "Politics," like several others that are far from the topic of the forum, that only contributes to an increase in spam.
I totally agree with you because reading and understanding the boards is necessary so that one would not have to make off topics replies and posts so everyone is entitled to any session they find convenient enough for them but for newbies, engaging more in reading instead of making posts or replies is also a good step to learn faster just as you stated.
I think every body has their favorite boards and and it depends on your interests, some people are more interested in the technical board to gain share knowledge about the development of bitcoin, some spend more time in their local boards and i have seen some spend their time in the gambling board so all that matters is achieving your goal of joining the forum.
For Newbies it is still the same, if they are more interested in understanding bitcoin technically then the technical board should be their home and also the beginners and help board. Knowing your goal and finding the appropriate board that suits your goal is the most important thing to understand.
Sure everyone is at liberty to post in any board they wish to so far as they have comprehensive knowledge of the particular board they are engaging in discussion but I am mostly laying emphasis to beginners because no matter how knowledgeable you are in any session, as a beginner taking time to go through discussions on a session you feel is favourable to you is important
