From Strategist's Personal Library:
Haha. I loved this part "A younger, more vocal, more online audience simply doesn’t like Mr. Leno’s show, which has gradually come to represent an entire pre-digital, Middle American culture that the Internet commentariat wishes would just get out of the way."
I had never run across the phrase "Internet commentariat" before. What a cool term!
I am assuming Commentariat would refer to the "[generally] younger, more vocal, more online audience"
with a heterogeneous mix of self-styled Bohemian intelligentsia. Although, personally, I make an effort to value all points of view, including reactionary, as part of a "healthy" mix.
Consider: I am sure we have all met people we considered to be "close-minded": but have you EVER known anyone to identify themselves that way?
