That's quite recent. Instant feedback, starting with the 24-hour news cycle and ending with social media clicks, brought on the bomb-throwers. In the 80s and 90s it was not unusual to pick up the paper and read an informed, cogent, well-reasoned essay about some topic that few readers might be interested in (and most might disagree with). All that's gone now, however. It's all just clan-based emotion-driven click-bait and grenade-throwing now.

I said I scan a ton of commentary. It used to be (ten years or more ago) that the majority would be, well, opinion pieces. Now only 5-10% or so are actually opinion pieces. Most of the time it's just cheerleading to people with more and more invective about things the audience already agrees with. There's really little value to be had.
