> I think if i were to discuss things face-to-face with some of the people here it may most probably end in screaming/yelling and fisticuffs

I had the same feeling, until some years ago I met up with some local HNers and lo and behold; they're nothing like what's going on here typically, just regular people who can have regular (but interesting) conversations :)

I'm guessing for many it's really hard to "read the vibe" when it's just text, and people take everything very literally here, while in real life, even people who write and behave like that here, don't actually act the same.

Maybe facial expressions, body language and more basically solves all those trivialities/nitpicking/arguing-for-the-sake-of-arguing issue, at the very least because those who perpetrate those things, actually can see the "what the fuck is this guy on about" expressions in real-time as they speak to people. That's my guess at least.
