This is a good example of why launching to the wrong crowd gives you a completely false impression of how popular your product is. It's one of the many things that makes marketing really hard. At least /r/frugalmalefashion seemed like a good fit on paper. It's worse when you see people talk about the thousands of visitors they got from a launch on HN or ProductHunt, mistaking 'people interested in product launches in general' for 'people interested in XYZ app'.
