I believe LinkedIn may have already reached its maximum potential and is on a downward trend.<p>Of course I'm speaking only from personal experience, but as both candidate and hiring manager LinkedIn holds next to no value for me. I see it as a commons that has been largely ruined by recruiting agents who are incentivised by their employers to maximise candidate throughput at everyone else's expense.<p>There is some residual value in LinkedIn groups, where peers can network for mutual benefit, but these pools of genuine interaction inevitably attract recruiting agents - if indeed they aren't already present as groups admins, happily lurking while candidates posture and parade.<p>But I'm not about to close my account (if that is even possible). I'm very fond of the growing number of endorsements I've received for Sarcasm and Bubbles.
