speaking from my own experiences, linkedin does not seem to have any more introspective text content than, say, facebook. from the commercial/influencer side, many have taken the AI route already by using LLMs to help write or spice up their posts. even for paid users, the site allows to help you write your bio or certain types of pieces for the past few quarters. maybe the posts of the yesteryear and like the comments section seems like a "valuable" source for them really. although it would be a bit more scary if this is for video and photos too, although besides the headshots it has also been a lot of AI content in the tech space lately.
