I found this web article interesting.
While the overall point is valid, I have to agree with some of the comments left about the article: It was bland, the photos were uninteresting, and really isn't about composition at all. This is more about perspective/point of view. That does take some composition into consideration, but there are better ways of explaining it than this.
Composition is about lines, shapes, texture, depth, patterns, symmetry, and general artistic rules of good design.
