As some may know, I am a self-taught video editor working in a small local television station. I was always interested in knowing more about my profession, so I spent many hours of my free time looking for information and good reading on the subject (and still do). Several years ago, I found this site, and I was pleasantly surprised it's still alive after so many years. If you are just starting in the field of video production I recommend you to read each of the modules, there you will find vital information if you're interested in making a living (or just a serious hobby) on video production. Do not feel disappointed with the site design. What really matters is the content.
