I had the opposite experience (illustrating that our stories are just anecdotal), but I don't blame Product Hunt at all -- I was grateful for the chance to be featured on their main page. My Show HN brought ~6K visitors in the first two days where my PH post brought <1K. I didn't know anyone, just emailed their team and... added PH to the extension (no one asked me to, just thought it'd be cool).

Admittedly, it was a bit humbling to see a cat "meow" soundboard quickly surpass my project on PH -- but like I said, no regrets.
