Yeah, I got it, but it might take a Brit or German! Unfortunately there are dismissive third-party comments like that sometimes, and seeing it grey (at the time) I almost voted down myself too, just then thought I recognised your username and double-checked.
One other thought actually - if you can still edit the title, you might get more attention from 'Show HN: The Danglepoise', since then people will know the author is around for discussion. Just anecdotally I would guess Show HNs tend to have more engagement/votes on average.
True, didn't really realise that actually, just read the rules. I'm sure I've seen similar as Show HNs.. but I guess maybe they had a GitHub project or whatever that tilts the scale.
(Also, I don't think you can do it by edit, but next time note that you can submit both a URL and some accompanying text.)
