It takes a special kind of project member persona to handhold a newcomer from the "asking questions phase" of wanting to be a programmer, to the "seeking answers for themselves" stage of being a programmer and if you're lucky you'll have a member of your project that excels at handholding a new user all the way up to the "gives answers to newcomers" stage, thus completing the unicorn life cycle. But these are rare and in only one instance have I actually meet such a member of a project.
