I am quite new, and I figured out quality comments are worth it on my own, but you added depth to that hypothesis. Ty.

One thing I would like to add: to me it seems that it's not only about how you comment, but also when. Especially when you have a new quality post out, you should be hyperactive commenting the post of people with a similar field of expertise to get their attention. A few might even click on your profile, and then maybe read your new post. One of the few ways a newbie can get attention to his posts.
