The way I interpret the modern use of "so" is that the speaker lacks the confidence to express what  they are about to say and uses "so" as an introduction to their comment. The scenario is that someone wants to say something and creates a slight pause by saying "So", "Right", "Now then", "I mean" and such unnecessary words.

Useless fact, facetious is one of a very limited number of words in the English language which contains all the vowels in alphabetical order.

And I believe that Rythmn is the longest with no vowels.

Think it's fair to say that a few of those words are not in common usage round these parts.

I'm shocked that you have such a limited vocabulary

[JasonB]

It's tragedious.
