You are probably already aware of https://shlinkedin.com/ but it is worth a mention just in case. I think you might enjoy it.
I dont understand even 1 post from there
You're lucky, since it probably means you never got hit with serious, high-level LinkedIn-speak. People speaking like this exist: I only had one or two interactions, but I honestly ran for my life and sanity as soon as I could. It's eerie, and both possible interpretations ("this guy speak like this for a reason (I'm not going to like that reason)" and "this guy honestly believes what he's saying (is he mad?)") are frightening. I feel really fortunate to only really encounter them IRL this rarely.
I basically cant believe it, until it is not in IRL . I thought people basically joke and try to be dramatic .
