Without knowing much about product hunt, I posted on a late Sunday night... woke up to my product getting some good traction. Someone mentioned in the comments that my site wasn't working right - and the link from PH had a URL query string I hadn't anticipated... which broke my product. I quickly fixed that and ended up getting #4 product of the day and loads of traffic (40K in a week) and link sharing. I decided, I should monetize the site...
