- Put a clear statement of what this thing is on the main page of the site (which should be the page linked to on HN). - Don't ask my to sign up or give you personal info without giving me a good reason; let me see a demo or at least something like screenshots/results/examples first. Related: what am I getting out of taking time on your site and/or letting you know about me? Do I trust that you'll deal with my personal info in a respectful manner? (Hint: No, I don't.) - If you are not a native speaker of English, then run the site by a native speaker before publicizing. Concerning the first two above: even when you've paid attention to them, you probably haven't done nearly as good a job as you think. I come to your site knowing nothing about you or what you've done; help me understand. For example, you say, "Unclear message about why I would use said app". Sure, make it clear. But first, pay attention to a more fundamental question: make sure that your site indicates that it is about an app. And be clear what platforms the app is available for. And how to get it. And does it cost something. Etc. (Idea: Find someone who knows nothing about your project, show them the site, and then ask them what they think it's about. If there is a sign-up, then ask them if they noticed it. Ask them what they think they get out of signing up. Don't give them any hints beyond what they already saw on the site.)
