I’ve been noticing people answering questions or explaining things with the preamble “so.” It’s become something I notice all the time now. It’s SO rampant. It bugs me! I did a google search and found that it’s been going on (and been noticed, notably) for a while now.
The problem is that you are what you eat. I keep hearing it, and now I’ve slipped into using it. It bugs me! I want to stop! Please correct me if you hear me using it when I talk to you, and I will check myself as I go

Nothing, with that usage. ;)
