I'm curious what other experienced people think about this article. I've been working as a consultant for about 5 years now and recently started working on a startup, so while I like working with a constant team (as opposed to a different client each project) and large projects (website, marketing, services, etc) I don't have the experience in starting a company and thinking long term about teams.<p>Besides not dismissing "grey beards" (which I don't tend to do, most that I've worked with have a lot of experience and resources to bring to the table, while most 20 somethings have lot of energy and usually a deep understanding of a small area of expertise.) is there anything else I should take away from this article with a grain of salt?
