These comments added nothing of value to the discussion. Asking why people voted a certain way is foolish at the very least because those whose voting so vexed you will have already moved on. The very people you demand answers from did not even hear the question. Everyone else is just annoyed.
The truth is that voting never makes much sense. In aggregate, people vote based on agreement or disagreement whether they "should" or not, and complaining about it is not going to change that. A post with a score of 50 could represent an intriguing and nuanced exploration of a topic just as easily as it could represent a strongly-worded yet vapid and utterly one-sided opinion. All that voting really tells you is that at least 49 people found it something about it emotionally moving enough to click a button before closing the tab.
I do re-check threads I've commented/ voted on. I assume others do as well and want to be held accountable: this is HN! I have no interest in spending time on here if this turns out to be another noisy channel.
I assumed some Google fan-boys voted me down initially, which angered me, nearly frying my development machine on a flash video (Chrome beta runs at 100% CPU with certain plugins).
If it's some technical reason that I've ignored, good for you. If it's passive aggressive behavior then not so good.
