I am new here myself but I would say that your assessment is mostly accurate. Keeping in mind that there are obviously a wide range of reasons for people to come and the threads range across the spectrum. Some come to learn others to teach.
I would say that the level of discourse can go as high or low as you choose. It is like walking into a party and realizing you are having a beer with a theoretical physicist or a biologist or Joseph Cambell.
It is a veritable gold mine of knowledge and wisdom.
