This is great – LinkedIn will limit your personal network to three degrees (see here – thanks Konstantin)! So no more introductions between people that are trying to network 4 degrees, where you do not know the person requesting contact nor the recipient. This is a major improvement.
I also liked the InMail option – whereby you will be able to reach people who are more than 3 degrees away by emailing them directly through the system. The recipient can accept the contact and reveal his/her contact information or reject it. The best part of this option is that the recipient will be able to see how many requests from the sender have been rejected by others.
The question is – how much will it cost?
