I work remotely so I had no idea. I'd have thought that unless you're in HR you wouldn't scroll a website whose primary purpose is to look for new jobs.

Much like X, it's what you choose to use it for. Papers are posted, approaches are debated, and loose groups form to align. It's easy to scroll past the pandering, but there is useful stuff in the dross.

But agreed, it is getting harder and harder to dig to the gems.

That is not the primary purpose of LinkedIn though. It is used extensively by a class of people who are generally decision makers and those selling services to them.
