One of the things I love about open source projects is they are almost forced to do this and it works great. Having designs written down and iterated on helps in planning and designing, and helps when its time to make changes. Being able to see why something was done and the arguments at the time can really help prevent people from making the same mistakes twice as they make revisions on a project.
