If we see lots of comments interspersed in a method, it is a good sign that the code cannot be easily understood. Break it down into lots of little functions with descriptive names, and all of a sudden our code reads like a very clear and concise recipe, and we find that the comments become redundant. Most comments that live inside functions are parasitic organisms, treat them with suspicion. Seriously? I've seen this a lot in the Ruby world and it works in a lot of cases but using it as a rule sounds Wrong.
