Someone should change the title of this post. I didn't read it for a good 3 hours because I didn't realize it was related to Rails.

  Me neither, but most people who run Rails apps that are somewhat significant probably do.

  I hate to say it, but if you're running a public facing Rails application, it's near imperative that you know what Action Pack is and why it's significant.
