That sort of thinking may have worked 3 decades ago, when Sendmail 5.67 was the latest and greatest way to move e-mail around, and pretty much all the sysadmins on the network knew each other by reputation, and posting "Hey guys, I can't seem to get this working, what am I missing?" was guaranteed to get you useful help. However, I haven't seen much evidence that it's been a workable strategy anytime this century. In particular, it would require a number of 800 pound gorillas who are mostly centered around increasing the success percentage to voluntarily choose a course of action that would lower the percentage - and they'd be relying on the set of sysadmins who did the *least* thinking about their configuration to fix their stuff. Phrased differently - did anybody in school *ever* voluntarily choose to work on a project with the least clued and engaged student in the class, in hopes of improving their own grade on the project?
