In particular:
> "Show HN is for something you've made that other people can play with. HN users can try it out, give you feedback, and ask questions in the thread."
> "If your work isn't ready for people to try out yet, please don't do a Show HN. Once it's ready, come back and do it then."
> "Blog posts, sign-up pages, and fundraisers can't be tried out, so they can't be Show HNs."
