One of the things I liked about the article is that it has you train for 4 different goals. You're not going to get 'good' at 1 particular thing but you get to enjoy 4 different types of lifting.
Unlike Crossfit though which mixes even more different types of lifting in 1 workout, it shouldn't make you hurt yourself for bad form as easily.
This is another article that should make someone think twice about Crossfit :

One thing I am looking at now is to see if doing 4 completely different workouts with also very different types of rep ranges/intensity would work better than say 3-4 workouts with the exact same exercises but then do like 1 of each in every workout.
