Having a mechanism to express your thoughts, whether publicly or privately, can be beneficial to the learning process. You try to express your ideas to others and see if you really understand it, sort of like the Feynman technique.

Beyond that, if its cringe to you or not worth your time, just ignore it and move on. Just because it's not worth your time doesn't mean its not worth the time of the author.

I totally agree. Im not saying he shouldn't blog as for its good personal expression, similar to a diary. Just surprised to see it on HN as for it seems more that the author is someone seeking validation vs discussion.
