1. I am not interested in jobs that focus on JavaScript, but I'd never say "No JavaScript".

2. when people ask for your CV, post a link (or if you're concerned about privacy, solicit requests via PM/email).

3. Your integrity, sillyness and attire are mostly immaterial to the job hunt. It's most appropriate for folks to make this kind of assessment during an in-person interview.

4. what is all this "nothing will come of it" business? If you think you can't get hired as a result of an HN post, I think you're sorely mistaken. Capitalize on these fifteen minutes. You've created some original, interesting content. The traffic you're getting to your site won't last, so strike while the iron is hot.
