I use linkedin for having a reasonable reliable connection to people from the past. I.e., primary school friends, high school friends, colleagues, etc. I've never used it for job hunting, but for the feeling that i might be able to get back in touch with someone i was close with at one point in my life. Basically, i just want Facebook without the feed. Linkedin admirably fits that niche. Admittedly, I hardly use it - but it's the ultimate fallback for when all other options run out. Apparently people post things there. But i don't think anyone holds it against you if you do not interact.
