If you're interested in learning, ask more questions. This thread started off with some dubious statements, and when that was pointed out, you dug in deeper and deeper. That doesn't inspire much confidence that you will appreciate someone taking the time to educate you. Hence, the terseness.
My first draft of that post was more question-based than statement-based but for some reason I thought the rewritten version was better presented. In hindsight that was really poor judgement on my part. Sorry for that. But I assure you that I'm very much interested in learning :)
The "digging deeper" was more down to responding to other people who had misunderstood my original comment. And lets be honest, there has been a lot of that as well.
edit: oh jeez, someone's been on the rampage with the ▾ clicking. I think it's time I get HN a break because the moderation on here has really been bugging me in recent months. I know it's a tired cliche, but I'm sure this community used to be less hostile. </soliloque>
