Just by way of history, the article was a mess until  cleaned it up to roughly its present form a few weeks ago. I think I am right in saying his philosophy was to not go into great detail in this article, but to give introductions to the main articles, which would then give the real details, otherwise this article would be huge. In my mind he may have pared back a little too much, or maybe the present sections could be kept the same length but better written, perhaps linked together a bit more tightly, but the improvement he brought was great. What improvements did you have in mind?
