For a senior coder, comments may feel redundant but for the junior coder, it helps. If they can't comment the program from beginning to end, they haven't thought the logic through enough to write clean code. And what I like about well written comments, it's easier and faster to either modify or have someone else "step in" with the coding project if necessary, and use to explain to a non-technical manager where you are and what you are doing.
