The linkedin cringe comes from this place.
there's the founder/ceo trying to brand themselves as a "thought leader" slop. stupid made up inspirational stories. grind/hustle motivational stuff. etc.
then there's the slop from employees. this is usually a multi-paragraph missive where they announce that they've made the hard to decision to leave company X for company Y but they learned SOM MUCH and everybody at company Y are ABSOLUTE ROCKSTARS and on and on and you just wonder "if all that's true, why are you leaving"
LinkedIn slop has a certain smell to it like no other spam does. I’m still puzzled as to why anyone does it - *surely* everyone from the cohort you wish to attract is familiar with it and sees right through it? Even for marketing positions I don’t see how this can translate to other, actually-profitable venues since this kind of content wouldn’t work anywhere else.
