I've just posted over at HBR.
This post was especially fun because I got to write about a topic that I find endlessly fascinating: how we connect with people, build a community or network.
It was also fun to draw on the research of Monica Mullick Stallings who I worked with briefly at Merrill Lynch: and with whom I have multiplex ties. (You'll know what I mean after you read the piece.)
If you are at all inclined, I'd love to have you click through to the HBR blog and share your thoughts -- I'm really curious to hear your take.
