I love the honest descriptions and mission you are driving on here. As the other poster said, a lot of it will come down to "experience is the best." (at least in my opinion too).
I see the value draw to younger people who aren't really sure what they want to do, or older workers who might want to jump to a new career path. Nothing beats candid opinions.
I don't see much you should add, adding more feels like it would try to make the product do more than it should; I feel it's great where its at.
Well done.
