Since there is often no way to differentiate between blatant promotional advertisement submissions (spam) and sincere requests for feedback on projects, Hacker News has "Show HN" submissions. You can find all the existing "Show HN" submissions through the "show" link in the top menu. If you want feedback on your own project, do your own "Show HN" submission, but you should read the "Show HN" rules [1], along with the main HN Guidelines [2] and FAQ [3] (linked on the bottom of every page). The HN welcome page [4] for new accounts is also good reading.
