So, this means exactly the opposite of what it says
When I was about 10 I had a teacher who liked to point out that when people said "a certain number of...", what they actually meant was "an uncertain number...". If they knew what the number was, they'd have given it, but they cover up their ignorance with this false certainty.
Every other blog post I read these days begins "So..." What does this "So" accomplish? In conversation it's an indicator that what is about to be said is in some way consequential, based on what has just been said. So why do blog posts start with "So"? Precisely because what follows has absolutely no bearing whatsoever on what anyone else was saying before. It's a way of interrupting the wider conversation with a jump-cut while trying to conceal the lack of consequentiality.
