how do folk here actually use linkedin?
i never been good at really networking, definitely fall more on the introverted side of the spectrum...generally, i really only accept invitations from people i know (or at least people that i have had a conversation with or know of), which is maybe limiting but it is also kinda weird to me that people, seemingly randomly, want to invite you "be in their professional network" and never actually link before of even after said invitation? is this just kinda casting a super broad network or do people actually use connections via linkedin to forge relationships?
#related: in my limited professional experience, it has almost always been the case where people get looks based on a recommendation or being found by someone attached to the hiring process (hr, headhunter, design director, etc.) and rarely ever through just applying to or waiting for openings...so i'm also wondering is it proper etiquette to hit up people in design (via linkedin, who would be total strangers) for insight into opportunities or should one just be looking to the hiring department people (agian via linkedin)?
