Can someone explain how this works and where the app is pulling the suggested links from? At first I thought it was showing existing links between different contacts, such as if two people have the same home phone number, then it would show that they are connected as such. But after looking closer, it seems to be different. I assume it's using my various hundreds of Google contacts to find links, but what exactly does linking a contact with something/someone else do? I tried once and linked my sister and brother-in-law, but it had the effect of removing my sister from my Contacts list altogether, so I didn't want that. I also tried using the option to link with a Facebook profile, but it brings up a text entry field and I have no idea what to type here. I tried typing my friend's name and pressing Enter, but that didn't do anything. So any information on this whole linking thing would be greatly appreciated!
