In golf course design and architecture, I don't think it is undesirable to have collaboration between similarly motivated individuals to produce a golf course that appeals to a wide audience. The collaborative idea certainly goes back to the craddle of the GCA endeavors. Colt and Allison, Cold and MacKenzie, MacKenzie and Maxwell, Ross and Maples, Langford and Morreau, McDonald Raynor Banks.... on and on.
In the modern era we have collaborations, even under singular names. Doak has a team, and if I understand their process, team members collaborate on ideas with Tom, and the reach agreement on various approaches to questions on the ground and what strategy to employ based on how they will take down or build up a piece of ground. Coore AND Crenshaw AND 'The Boys'. Routing, shaping, and even grassing schemes are to that extent collaborative discussion with give and take, with the person whose name(s) are at the top of the firm's letterhead, making ultimate decisions.
Writing an opus of literature seems more naturally in the realm of singular effort, dispite the many examples like Peter offers of collaboration. But, the question of the popular embrace of a collaborative effort in things like pop culture might be explained that the collaboration might be mostly of a commercial nature and designed to appeal to the widest audience using more conventional or pop trendy literary devices or employing pop ethos or philosphy in a story line to the extent it is written to the lowest common denominator, or dumbed down, if you will. Thus the phrases and lines in the Good, Bad, Ugly and other pop culture iconic movies and such.
Dumbing down yet gussying up a golf course with purdy stuff might be motivated by the commercial interest and collaboration to find the lowest common denominatior. Then again, there can be the vanguard of GCA, or the 31 flavors, and confidential guides of the connoisseur who doesn't seek the common or banal to trip his trigger in pursuit of the passion for inspired and challenging golf architecture and design.
