When Success is Born Out of Serendipity - HBR article

[Steve King]

When Success is Born Out of Serendipity can be found here.  It's written by the author of The Medici Effect, a pretty good book on the role of diverse viewpoints in innovation.  

Also on HBR is Never Say No to Networking, which is about creating serendipitous collisions.  

This whole networking/ collisions/ weak ties/ serendipity meme is really getting a lot of attention these days.
