Is the posting of a book chapter different from a blog post? The Show HN rules say blog posts can't be Show HNs. And the reason given is they "can't be tried out".
Yes, it's different. A book (assuming it's a real book and not something slapdash) is a major piece of work. Obviously some of the finer distinctions (e.g. what counts as a book chapter vs. an article) can get pretty arbitrary. But the broader lines aren't. The intent of Show HN is for people to share what they're working on. If we applied the strictest definition, the only thing anyone could easily 'try out' would be web apps, and that's much too narrow.

It is, I hope. But if you're prefer I post these without "Show HN", I'm happy to. I thought it was worth doing it to make it more obvious that I was self-posting, but I can not do that if that's what others would prefer.
