Because it's invaluable during a job search. A person can easily apply to 50 jobs in one evening through LinkedIn. A decade or so ago, that could take a full week of work or more. Each individual company you applied to would require you to register on their job board and fill out a long application where you re-enter the information from the resume you just uploaded. It could take an hour or two just to apply to a single job. And that's only after you lucked into finding the job posting in the first place because postings weren't centralized and searchable like now with LinkedIn. To your point though, I do pretty much forget that LinkedIn exists if I'm not actively in a job search.
