yeah, the most useful resource wasn't even the recruiters (which was occasionally helpful, but none of my career roles were gained through LinkedIn Recuiters). Having a way that wasn't twitter to connect and talk with old co-workers and colleague was invaluable.
My last role was gained by reaching out to a colleague I haven't talked to since college and asking about the role I applied to, and he was nice enough to give me a referral (I honestly wasn't expecting a referral. it was easily 5+ years since we last interacted, didn't talk that much in college, and I wasn't the best student to begin with). I doubt he posted his roles on Facebook so I never would have thought to contact him otherwise.
