summary of the article was much better than the article itself, which was cluttered with lots of quotes and pictures and lengthiness. Summaries that are better than the original articles are hard to do, hence, upvote.

It's not very hard to do when the original author is Mike Darwin. The man really needs an editor. Consider "Doing the Time Wrap", which looks for all the world like someone wrote 2 or 3 amazing, wonderful essays on completely different topics, and then decided to cut and paste random sections of them to form a single article, with random song lyrics thrown in for good measure.
