"First, it is your responsibility as a learner to decide if something makes sense or not." That applies only to the most trivial of subjects. Most complex things worth learning are so opaque to complete outsiders that it's impossible to discern good advice from bad. In the most complex domains it all appears gibberish, and the only thing that you can trust is that the teacher knows what they are doing, and that in the end it will all make sense. Teaching things without any understanding of the subject is folly, and is actually dishonest. Just like portraying as a "healer" without any concept of the cure or the decease is dishonest and unproductive. Yes, you can help people without medical degree, for example in giving physiotherapy, but you really need to know your muscles, joints and therapies then. The role of the teacher is holy and venerated, and for a reason. Please don't make it cheap by saying "anyone can and should do it, and let students pay the prices". Anyone can and should do it, but only after they have paid the price to master the subject in sufficient complexity to actually offer any advice worth sharing. Informally helping colleagues is cool, but in that case you are sharing much more common context than in a semi-anonymous blog post.
