First sentence

> 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

Feels like it fits exactly my understanding? Not company vs person/project, but press release/announcement vs something to play with, something easily accessible and tryable, detailed?? And it goes much further that it must be something like this.. and no mention at all that this is the necessary disclosure if this is your article, newsletter or similar.... this one here definitely not a "Show HN"!
