Ask HN: When's the best time to post to HN?

A good link will get votes, and rise to the front page. You have to have faith in that process -- and in the link.

Also, Hacker News readers tend to have a really narrow focus on the world of professional programming. I think part of submitting links is accepting that the community may just not be interested in every link, and being okay with that.

When you've got something interesting to say.

Or is your question really "When's the best time to post to HN if you're chasing meaningless-internet-points or scammily begging for SEO backlinks?"
