I have never done a Show HN, but I have written and spoken before about the fact that this varies a great deal. I have had posts get thousands of page views. I have also had posts get largely ignored. http://micheleincalifornia.blogspot.com/2014/01/unimpressive-hacker-news-post-mortem.html http://micheleincalifornia.blogspot.com/2014/01/unimpressive... There are a great many factors that impact how much traffic you will get from HN. Do not assume that posting something here will cause your site to be overwhelmed with traffic. That can happen. But lots and lots of stuff gets posted here and largely ignored. The only way to know which it will be for your project is to post it. No amount of surveying will give you a meaningful answer. Best of luck.
