And I realized that people like us, who do communicate well via writing, can come off as very scary and intimidating to those people.

Hmm. I wouldn't want to make my writing less clear, though, in order to be less intimidating. I definitely do change the words I'll use, depending on context, though.

Actually, my problem with non-friends tends to be that I can't talk / write Business Bollox. People at work use words and phrases that just... don't enter my head. :) (Although it's not too bad, where I am now - I've worked in offices where it's like they're speaking a different language. And such a boring language, too.)
