So, I listen to podcasts on the way to and from work, and let me tell you, nothing is more irritating that hearing some random Microsoft employee or intern start every sentence with "so".
So, if I ask an MS employee if the sky is blue, the answer will probably come back as "So…. yes." Or alternatively, "So, not today because it is cloudy, so however tomorrow it’s supposed to be sunny, so it will be blue tomorrow".
So surely you can see how irritating this gets, right?
So, they use the word so so often it becomes mere audible filler. So it’s kind of like, "um", except "um" isn’t abusing the English language quite so much.
So, see what I mean?
