I like to think it was a Show HN, about a remote isolated browser product, but actually I found that spikes in sales came more often after I made some random comment that showed I'm an expert in that tech, not trying to sell something. What I found is that comments, not posts, led more reliably to inbound sales interest that converted into revenue.
