Glenn_nl, thanks for the link. Twelve prolific posters account for 65% of the shares – reminiscent of modern inequality of wealth.
But we can’t really blame the twelve. It has been the big internet companies that have promoted such stuff for decades and made obscene amounts of money doing so. It’s such a cynical exploitation of human weakness, much like junk foods loaded with fats and low fructose corn syrup, but far more profitable and they don’t even manufacture it themselves.
