> 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.
> A Show HN needn't be complicated or look slick. The community is comfortable with work that's at an early stage.
> 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.
