I have tried open sourcing other stuff, and it's been completely overlooked. I guess you have to promote it somehow. But I've tried putting stuff on GitHub, and I don't think anyone ever looked at it. If it were to have an audience I'd do it.
Perhaps just put it on github, and just drop the link to it whenever you mention it in a comment here?
(Or just put a link in your HN profile, people can click through that easily.)
