advantages of writing blog

I think, writing blog on the site after our lessons and answering some questions is useful for us to remember knowledges that we'd learned in lessons. It creates a feedback. Sometimes ıt seems difficult that trying to remember what we learned or reading our notes etc. Therefore, answering the questions by blogging gives us a chance to remember main lines of our knowlegdes. Moreover, to me, writing is a good way to obtain our learnings permanent. Also we can have a chance to see different answers, that are supported different ideas, opiniuns or evidences, to same question.
