Keep in mind that the topic is thinking in writing (vs "volatile" thinking).I average 25-30 notes per day. Even if I'd ignore it's relatively specialized math and CS, it would take a rather large crowd to review and a lot of context. Meanwhile, like with coding, writing and re-reading notes forces your mind to lay out things with more structure, often uncovering loose ends. I agree that public forum like HN/Reddit is a good, scalable way to review (some) ideas, but it works for a fraction.
