Fun with dynamic features: MSN article template

As I was skimming through the morning headlines and tweetdeck channels, I came across an MSN article about the first hurricane of the season, and was struck by how many dynamic HTML features had been packed into one article template.

Rich interactive experience, or dynamic templates run amok? What do you think?
