Your posts are "dead" (I can seen them with showdead on in the settings) - that happens when they are auto detected as spam or otherwise undesirable. One reason this happens is when you create a new account and then post something immediately. Usually if you participate on HN a bit, your post will be allowed through. You may also want to view the rules of Show HN as well as other submissions and make sure your post is appropriate.
