HN does not generally result in a lot of targeted visitors who are going to be long term users of your product.

However, I find the feedback in the comments section to be hugely valuable. HN readers are inevitably pretty savvy about startups. While you can get a lot of criticism - it can be quite constructive, pointing out things everyone else you show the site too has missed. Getting onto the front page is vital to get any volume of comments.
