I strongly suggest not changing that word. The connotation with minimal is that you are avoiding having too much in the way of comments, and I think for working code directed at working programmers, that is correct.

Follow the thread at Re (tilly) 2 (disagree): Another commenting question, for explanation of why it is important to be minimal. (As I always point out, behind the scenes we were trading /msgs that are unfortunately not public record, and were much friendlier.) Read that and get back to me on whether you think that minimal is the wrong word...
