I deleted my account from LinkedIn almost two years ago. Primarily because I never saw the balance of my effort with nurturing the network being paid off via benefits that such a network is supposed to give.
Furthermore, the only real network I believe in is the physical/real network of friendships, acquaintances, colleagues which, by my experience is vastly supreme to anything virtual. I’m not saying people should not use LIn, many see great gains through it and I commend them for it. But not me.
I just love the analog.
