Ha. Sorry about that! I usually only downvote things that are materially wrong or offensive but I know lots of people use it as a vote to say they disagree. Your comment also had a sort of "typical American" derogatory feel to it which you can only get away with until someone points it out. Most people reading HN are probably Americans you know. ;-)
As for the price movement, it is relevant only in that it is exactly the sort of knee-jerk reaction that Apple was avoiding by announcing on a holiday weekend. The movement we see when the market opens will be different given that people have had time to absorb the news, even without the earnings announcement.
And sure, the price movement was a "knee-jerk" reaction, and the price on US open will likely move higher - or lower. An instant drop followed by a flat market pretty much is a textbook example of the stock market reacting to unexpected events, though.
Maybe: "Don't rant about ignorant Americans to Americans unless you're willing to burn karma"? I guess they're all asleep now so you can get away with it. But this one is in Tokyo!

Trading on Xetra was quite active yesterday, but certainly less than a typical Nasdaq day. You should not discount that price movement as irrelevant.
And Gruber's point on earnings releases was a separate one, IMO.
