My only issue is that I feel, as an independent contractor, I’m obligated to maximize my potential in acquiring new customers. I don’t yet have the luxury to shut down an entire channel for new leads, despite the fact that LinkedIn has actually done very little for me in that regard. On top of that LinkedIn has become so ubiquitous that it’s actually become a standard question during some interview processes to ask for my profile. I feel that “I don’t have one” because of “principles” is never a great opener when you just made a new connection with someone.
The only other real tangible benefit I get from it is knowing about job changes my friends have made. I'm in my mid-30s and most of my good friends from University are spread across the continent. I'm lucky if we talk to each other a few times a year. So having the ability to passively learn "Oh hey, Jonny is now at Google" is valuable to me because I now know I have good contact at Google.
