I’d say it’s a nearly universally understood—though often probably subconsciously—way to attempt to change the subject or redirect it more narrowly. I can’t think of another more succinct formula that accomplishes that.

Actually I vote for OK.

I take it as a way of picking up from a statement made by someone else and drawing a conclusion from it. So, (LOL) the use of "so" is like the continuation of that statement and is used to emphasize that point.

And, have you noticed the increasing use of "and" as the first word in a sentence. I never do it but many others do. ;)

“So” also establishes what came before as settled “fact” (”taking this for granted we will now consider...”).

In Japanese, I was taught that if you make a presumptive statement, you should end it with “isn’t that so?”.

I have never really given it much thought and have been trying to reflect on my own behavior. I do a lot of speaking.

I can see where it would indicate a continuance of thought from one person to another. But I have to agree, now that I think about it.

So, in line with your thinking, speculatively assuming that your premise is true and the inquiry is righteous, I guess I agree.

In political matters, I think you are correct. However, in the discussion of commute times, the fellow was being responsive to the question. It was as if he were substituting "so" for "uh." The problem with that is that "so" is a real word with rules for proper usage. "Uh" (as per Obama) is a time filler to craft out the next lie.
