I believe its usefulness is for people looking for work.
Mine was one of the accounts that got hacked due to their insecure systems a few years ago so I deleted my account. (Apparently the hacked account info has recently been openly for sale and I have noticed spam coming to my old linkedin email address).

Same here lots of junk purporting to be them but I closed the account 2 years ago now.
I thought it was really for nosey people to be honest and left after 3 months, I'm not interested what people do for a living per se.
