I worked at LinkedIn (briefly, before retirement) and the product had been useful to me for years before that, so I used it a fair bit but not much anymore since it doesn't serve any of my current needs. There were always awful million-view posts written by humans, useless influencers promoted by the algorithm. That was always garbage, but to an LLM those posts look like success, because engagement, so the LLM tries to replicate that garbage, does a mediocre job, and the result is this sort of weird garbage. Basically the LLM appears to be high on its own supply. Problem is the viral stuff was always what made me want to run out of the room and lock the door, so even if the LLMs did a better job of replicating that garbage, it would still be garbage, just a little less weird.
