Well, remote job isn't exclusively connected to linkedin and personally i think that remote jobs are going to become more and more common with time. Linkedin is, mostly, useful for headhunters and people who want to sell themselves (which is totally legal, but it's personal choice). I've deleted my linkedin account and doing just fine with one important addition -> don't have to pump my ego on profile and live all that shit related to virtual narcissism. So, if you ask me, it's much better in mental sense.
I don't know what you mean by 'better in a mental sense'. I have my LinkedIn account and log in at best every 2 months. I don't even realize when I have internal linkedin notifications. People contact me by email, not by linkedin.
I think deleting your LinkedIn account is a net loss, what's the downside of _having_ a LinkedIn account?
