Code Readability is maybe the most important part of producing reproducible research. If it's impossible (i.e. very costly) for somebody else to read/understand the computer code that underlies your results, then the odds are that they will never be able or willing to reproduce and check your results. This is a big problem if we want to produce credible results. (Credible in the sense that not only you by yourself believe in what you found, just because you are the only person on earth who understands what you have done.)

If you don't think that this is important for you, think about the possibility of collaboration with somebody else: The quality of collaboration will depend critically on your team understanding what everybody is doing.
