Meaning, the product hunt results shown are the absolute best result you could hope for and most users will receive a far smaller amount of visits. PH gets a bit of hype because its invite only and people assume it has a big impact, but for most folk it would be much more impactful for their launch to even be on a smaller tech blog like Read/write or recode.
For the average person who gets on PH and gets the normal amount of upvotes (around 10-20 ) you can expect a blistering 250-500 visits. You would get more traction just posting a comment in a HN article. PH seems more powerful because its invite only and has tons of hype around it, but it does not deliver on results yet.
Surprised that HN numbers were so high, but not surprised that Techcrunch was number one. They still have a great share of the market when it comes to initial exposure.
