For example, I believe days start at 8pm PST on Flickr (can anyone correct me if I'm mistaken) and there's a power-user perspective that will wait to post things so that they can get a leg up on the "interestingness" algorithm.
Anyhow, this post makes me smile even the second time around.
Yours was "787 spells 7-8-7", which is not as simple to understand as "Dreamliner spells out...". Instantly, this headline catches enough of my attention to click on the link.
For headline copy, sometimes it will help to search Digg/Reddit and see which keywords people have already clicked on the most. This applies to email subjects, website CTA, etc.
sorry man, it was just the link I got. I'm all for first poster credit and respect, just sometimes same content can be generated from multiple links etc and stuff gets messed up. Annoying but you know how it goes.
On the time of posting thing...I know someone created a site to determine the optimal posting time for HN.... I have never used it tho! It's just naturally there'll be hotspots in the day based on simply where the majority of HN readers are from and the waves of social network activity.
Anyways, a good link indeed. A fun Friday afternoon share -- Great that the FlightAware guys are watching this and contributing too.
Also, re: titles -- yeah, descriptive titles always -- I try to do that, since I appreciate it when others do
