Couldn't agree with you more, many posters do a great job of in depth tuition, with up to date information & we the audience get a chance to ask questions, dig deeper, offer suggestions relevant to every move you make on your model, cant do that with a book or a video.
You teach, we learn, we ask questions, our posts go up with our knowledge & one day maybe I will be able to answer someone's question (of course there will be someone who knows better) so we ask more questions.
