What Queen613Torah said. She is so right. I’m talking to her! Can she hear me??? 😛
To answer the original question, I think it really depends on the setting and circumstance. As Mr. Kessin has pointed out (please forgive my accidental irony), in the high tech industry, addressing people by title is not the norm. I’ve known people who practically insisted I call them by their first name, and when I prefaced it with a Ms. or Mr., it sounded weird and it looked like it wasn’t received well.
I actually didn’t know that about Israelis and African Americans. Y’know, that probably explains why Israelis think I’m stuffy and weird. I knew people who called their friends’ parents by their forenames, and I was rather scandalized. It’s not a practice I’d adopt, since I think it diminishes the kavodability of the person you speak of/to. (I think I just invented a word.)
Even in a public school, I don’t think you get to address your teacher as “Joe,” rather, “Mr. Schmoe.”
