I disagree. When I re-launched Artpacks.org at the end of January, I did so with a Show HN. I stayed at the top of the ShowHN page for most of the day, and was in the top 5 on the home page for much of the day, too. For the day I launched, and one day after, I received 4.5k uniques, about 80k pageviews, and had 90-120 concurrent users through a large part of the day. When I launched SendToMyCloud.com a week later, I barely touched the front page, and had about 1/3 that traffic. I attribute a lot of that to the type of site (content vs app) and the amount of free content. I did get lots of signups via HN, despite the fact that HN users didn't fit my target demographic. In both of these cases, after the initial surge was over and the sites were off the front page, the project got a lot of long-tail traffic coming from /show.
