The Q&A with Bram is interesting in that for such a widely used editor, Bram and his approach to maintaining Vim seems very down to earth and philosophical. Some of his answers about working with contributors, and having a plan (regarding how features will appear) are simple but instructive. This is as much about maintaining a large open source project as it is about Vim specifics.
