As a disclaimer, I do not actually use it, and not all its users are like that, probably.
But I am going to trade school once a week right now and had several classes on how to manage your own page and turn yourself in a personal brand (yuck).
My area is design heavy but I kind of wandered off so I actually do fullstack web development (ain't good at it but it is what it is) so it's not as relevant to me anyway.
However, our teacher made us watch LinkedIns own training videos and other sources that all just tell us to spend several hours every week and to engange with the community. Influencers make it sound like it's vital and I just watch them and they are SO fake and gross to be around.
Professionalism is important, yes, but I hate the corpo-oriented fake plastic influenzer stuff. It just feels like your job creeps more and more in your actual life by marketing yourself in such a way.
But maybe I'm wrong, what are your experiences with that?
