LinkedIn is for professional networking. If Facebook had the equivalent of Google+'s circles to segment your friend list by type, LinkedIn would be unnecessary.

LinkedIn is for professional networking. If Facebook had the equivalent of Google+'s circles to segment your friend list by type, LinkedIn would be unnecessary. But since they don't, LinkedIn keeps me connected to people that I don't want seeing my personal updates and people that I need to contact when looking for work or trying to fill an opening I feel is high quality. All the posts and reminders are worthless to me and only serve to annoy me. It's the professional graph and messaging that I find valuable.
