Entrepreneurs generally need to be competent and being an entrepreneur generally gives one some degree of autonomy compared to a regular job. You also pretty much need to maintain decent relationships to people if you are going to thrive as an entrepreneur. I don't necessarily mean intimate relationships. I am sure plenty of entrepreneurs are basically workaholics and plenty of people here have indicated that a start-up typically leaves little time for dating. But there has to be some outreach to the community/large world and PG has compared cofounders to being like a spouse, but without the sex. So it seems to me that if you have a cofounder, you do need to have some basic relationship skills in order for the business to succeed.

Maybe I just have a different take on the article than you do? Not sure.
