Can one safely ignore all these "Business" networks? Wonder what people get out of it.
One of the weirder things I've experience is people "endorsing" my skills. Many of which are skills they've certainly never seen me use. I assume they were doing it for some sort of reciprocal endorsement, but I don't want my name attached to someone's skills that I know nothing about.
The endorsements are a particularly bad move by linkedin. I've been endorsed for all sorts of things; Knowing what I've been endorsed for, I don't know why anyone would assign any credibility to those items on their website.
