I've made my first ShowHN post and was excited to get some feedback about what I am building (https://news.ycombinator.com/item?id=36283179). But after posting it, it got zero engagement. I thought that sucked… but then when trying to find the same post I realized that it was never made public. I can see it from my account, but it is not visible if I check from my friend's account. Do these posts go through manual approval?
