It's also not clear how much it helps. I believe HN penalizes overly controversial posts, and it uses quantity/frequency of comments as a signal of controversy.
I've posted a lot of threads here and you have no control over what people will find controversial or not. If you post a thread and it hits people's nerves it generally happens accidentally. And "profiting off it" is always going to happen if you're posting your own work. So in the end I don't really think it says anything.
