How does this keep happening?
Over and over again people create some statistically significant way of measuring a difference in the length of responses.
Why the obsession over that metric? People in the twitter replies going on about how that shows it's getting worse.
For me, the shorter responses are the better ones. It's specifically in my personal instructions to reduce the length of responses. In saying that, sometimes I want longer. Then I specify it so.
It's "cool" that it has different response lengths seemingly based on its perceived date. It doesn't make it "better" or "worse"
