Answer: I misunderstood the submission prompt, thinking my comment would be attached to the post and not lost below. I linked that as a halfway-there example of what I want, and also because I'm a slave to SEO and HN ranks posts higher if they have a link.
You can edit the title of your post, or if it's been too long for editing to be an option, email hn@ycombinator.com to ask dang to do it for you. I had a similar reaction to others. Ask HN posts are supposed to just be a question, not a link to a site.
Looks like a decent site.
