emergent social phenomenon from the many-to-many, always-connected Internet
A sardonic expression referring generally to slightly dystopian emergent properties of the mass of human minds being always connected in many-to-many communication via the Internet. Also, the sardonic reverse side of the "wisdom of crowds" coin.
The optimists who invented the Internet and build the early web thought it would be great if people could more easily connect.
They failed to properly anticpate that psychopaths, charlatans, and authoritarians of various flavors, including some we thought had been defeated in famous wars like the American Civil War and World War II, would also find eachother, unleashing the meme equivlent of the zombie apocolypse.
