The first thing you should do is post a Show HN right here. Judging from your other submissions I assume you are talking about your fapnite.com thing? I mean, your app's potential audience is insanely large, so I would put a lot of effort into having a good SEO presence. With a good listing on Google and Bing, traffic comes automatically.
Yes, I've done the Show HN. I'm already working hard on the SEO, but it's difficult. Any other ideas?
Product Hunt?
Yes, and use Preview Hunt to make sure everything looks nice.
