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.
