I once reluctantly read an article about rewriting code from scratch. In the end I was convinced that it was in general a bad idea. I wish I could point to the article and may dig it up, but his point that sticks in my mind goes something like: all developers are, by nature, designers and always look at code and think, what a mess, I could rewrite that faster than learn how that works. Code that has been around a long time has gone through invaluable time of testing and fixing. You may not understand why things are done as they are, because you don't know all the scenarios the code operates correctly under. All the little tweaks for X to work while not breaking Y are expressed in the code, but not easily evident. Rewriting code throws away all that knowledge and experience.
