> Personally, I find it infuriatingly annoying how many emails I get

And I find it infuriatingly annoying when people post waitlists as Show HN when the guidelines specifically says:

> 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.

> Off topic: blog posts, sign-up pages, newsletters, lists, and other reading material. Those can't be tried out, so can't be Show HNs. Make a regular submission instead.
