So bad

Something that annoys me ...
Have you noticed that many people now start a sentence, usually in response to a question with the word so, followed by a pause.
An example:
Q. What do you think of this or that?
A. So (pause) I feel that etc.

Typically it is the older well educated 'youth' eg. 25-35 who start a sentence with so.
I frequently hear it during TV interviews.

It is so bad.

But, who am I to complain?
I remember when growing up, sentences were commonly ended with but.
Or if you came from Queensland, you ended a sentence with hey (pronounced hay).
I still drop one now and then.
