I've just got back in touch with an old friend via LinkedIn.
Prior to accepting the connection I saw that he was already a 3rd degree connection of mine and some of the connections were unexpected. So when I first clicked on his profile I saw:
you | V John Smith Peter Jones ... | V My friend's connections | V My friend
So, just to repeat, some of the people who are 2nd degree contacts of my friend were completely unexpected. For example I worked with "John Smith" in the last couple of years and can't see how he's connected to my friend who I haven't seen in at least 10.
So I need a way of seeing "John Smith's" and my friends common connections.
