Agree with this, unfortunately. I have a coworker who routinely calls people without linkedins "sketchy" and obsessively looks everyone else, vendors, functional area colleagues, etc up on linkedin. I didn't have a very fleshed out linkedin myself because I value privacy and was surprised how biased some people are about it. I've also seen candidates who have otherwise passed interview panels get veto'd because the dates on their linkedins don't match their CVs.
