You could equally make the case that HN attention is controlled by California night owls. I'm usually awake till around 3 AM PDT - that's 6 AM Eastern. So while the east coast is sleeping, I'm upvoting stories on the New page.
but after my question stayed virtually unnoticed, i started to think, what are the statistics of what time and weekday is the best to be noticed, if it's not Apple, Google+ or Microsoft.
How much California night owls are there? :)
