I was pretty excited a couple of years back when some bigger news sites explicitly turned off their comments saying they only generated distracting noise and added no value.
Then, after that I can rigorously filter what I see - on Reddit I have multireddits that I care about, and set those to Home using Apollo to browse, and I keep only generally positive sub-reddits in there.
I think there's huge value in going out of you way to block negative noise in bulk. Same reason I deleted Facebook - don't invite in the noise, and don't engage with trolls.
It's the same old strategy - the only way to win is not to play.
