How do you find out / when is the right time of day to post to HN?
One analysis I like is from 'minimaxir: http://minimaxir.com/2014/02/hacking-hacker-news/
There's also a Quora answer: https://www.quora.com/When-is-the-best-time-to-post-on-Hacke...
And wouldn't you know it, a submission on Hacker News itself for a post entitled "Best Time to Post? It’s Irrelevant": https://news.ycombinator.com/item?id=9426040
I'm sure there are others as well.
