But I think you've landed on choosing your own way, when really you should try and match the vocal tone of the other person. After all the point of communicating is to get the other person receptive to your point.
And this goes both ways, I think overly perky and chipper people need to understand introverts and low-energy communicators, and match their tone as well.
If you’re invested in getting something out of a conversational partner, it’s obviously best to write in a way that sounds like a thought they, themselves, could have had— in fact, are having. And contra 'ketzo’s original point, I deeply appreciate that so many we-have-to-say-mostly male tech stakeholders purposely don’t massage their language that much, and thereby make their brains that much easier to hijack.
I bring my effusively positive personality to HN largely because I don’t have any real motive or theory of change, other than possibly making it a slightly more comfortable environment for people who will read my comments precisely as written.
Oh, I’m so curious if this comment sounds more sincere to the reader :)
