There are plenty of valid uses for all the social medias. I use Facebook (my only one) to keep contact with my poor friends who can't afford a phone or simply very old school friends who I'd never text but am marginally interested in their life.

But there are many men who use LinkedIn as god and those connections as real major things. Its a huge part of "Hustle Culture" and guys whose entire existence is to use and abuse it to groom impressionable young men into being slimy douches whose life revolves around money for zero value ventures (that rarely work) and other nonsense.

Its like Discord for 20 something dudes with a lot of spunk but no sense.
