But whether this is a trait of a successful entrepreneur is not so clear. I'm not saying it isn't so, just that the poster could be biased by the YC wolfpack experience. Janus Friis and Niklas Zennstrom, for instance, weren't wellconnected when they started out with Kazaa and in the early days of Skype. I have several friends that are lone wolf entrepreneurs, and don't have many close friends or business associates in the strartup world. And some of them are very succesful.
