If the post was Show HN: "product name" then I wouldn't click it since I don't know if it'll be a waste of time.
Interestingly, a few startups have been putting "Show HN" in their titles even when it's especially unwarranted (i.e. a product that's been on the market a long time) for that Hacker News SEO.
