Is Starting a Sentence with 'So' Really a Grammar Mistake? Let's Discuss!

I have noticed that many professionals are now starting their sentences with 'So.' For example, "So, I would like to state..." Actually, starting sentences with a conjunction is not grammatically correct. What do you think? Check out this post: http://news.bbc.co.uk/today/hi/today...mber_265348014

The Use of 'So' as a Conjunction

"So" is used to join two sentences because it is a conjunction.

Yes, that's exactly why it should not be used at the beginning of a sentence. As (Cite Contribution) rightly pointed out, it has become a pseudo-style statement. In our public speaking classes, we call "So" the new "Um..."

So Far, So Good!
I am surprised that there are no voices of dissent!

So, should I conclude that people no longer value good literature or the versatility of the English language?
So, should we restrict our thinking and knowledge to the fact that "So" is just a conjunction?

So, it implies no one has heard of "so" being used as an adverb, as in: "I am not so good as Sachin"; "I am so glad to see you"; "She was so angry..."; "I do hope so..." etc.

So, let us put this argument to rest.

Warm regards.
