This is America, where we ask strangers, "So, what do you do for a living?" as an opening question because income generation is the most important thing about a person in the USA.
What else? Oh, I'm married. Cool. I live in a house. Yeah. Exciting.
I don't think "how people talk to strangers" is a representation of what people in the culture care about.
I'd also find it a bit weird (edit: or awkward) if someone started by asking what I love to do:
Is this a salesman or a recruiter?
Maybe a teacher?
And what should I answer that wouldn't be weird? "Volunteering for Troll patrol at Internet forums"?, "Writing Java"?, "Sleeping"?
Honestly the weirder the better. Its a great icebreaker.
It's a lazy one, but so is remarking about the weather or mentioning something about current affairs.
