Basically I don't think it's something you can do in the presence of a thing like twitter because of the participants whose goal isn't communication.
Which is fine. The wisdom isn't lost, its just not as widely available.
It's not fine though. Our political and economic spheres have been run by the swine for too long, and the planet's back is breaking. The second order effects of only giving the brash and thick-hided a voice in society are everywhere, causing permanent harms.
Let's start making space for the wise and sensitive types, and make pearls abundant.
Print the wisdom on thinly-sliced trees and place it in a location which requires someone to get out of the house and engage with their community.
You seem to be implying that this is a recent phenomenon of some kind though and I don't think it is. Just something to keep in mind! Not intended in the spirit of a damning critique or reason not to try.
Pretty recent, in the scheme of things - only the last few thousand years or so.
I do think we can turn it around; I mean, we fuckin better.
