I find Ask HN to have the poorest signal/noise ratio. But the signal is really good when it happens, so there's a skinner box effect, that makes me go here first. Show HN is a different environment and very little is useful, but still better than Product Hunt. There's a lot of interesting/inspirational stuff though. Main page is nice at times, but also full of people who neither read the article nor understand the topic. Most of the time I skip the top comments (which are often unpopular opinions like "bitcoin is ponzi") and dig around the middle comments.
