No one _ever_ even considers "algorithms" in the CS sense here (such as "sorting"), and even bringing that notion up would be deliberately dumbing down the discussion (yet it keeps happening in this thread over-and-over-again because people are for some reason very "well ackshually sorting is an algorithm").

"Algorithm" in this context is very clear what it is. It is not what the word means in Computer Science or in general. Just from the context and without any clarification needed "algorithms" in social media means "addictive personalized feeds".
