I actually think it's a bit dangerous to try and understand SV from HN comments, in the same way that trying to learn about an event by watching a fictional adaptation of it can often confuse more than educate. The goal of the comments here aren't for SV to chat anymore and it hasn't been for a very long time, for better or for worse.
Twitter is closer to what you'll get among founder and hype circles in silicon valley, but even that isn't a good pulse of what engineers here actually think. The public web is just too adversarial a place for most folks to want to hang out anymore and silicon valley has been so deeply politicized in the news that a lot of people just don't want to air their opinions in public anymore. My suggestion is to save up some money and just come here and visit for a week or two, go to events, rant to a few graybeards, that kind of thing. You'll get a much more authentic look.
