Dear tech reporters: please, please add the word "heuristic" to your vocabulary, and never, ever write another article where the word "algorithm" and mentions of social media both appear in the same piece.
(NB: adhering strictly to this will in theory lead to some false negatives, but that's vastly preferable to the status quo we're currently living with, where every dipshit who knows how to pronounce "Facebook" is yammering about The Algorithm. Knock it off already. Please.)
