I like the fact the each "webisode" is divided into blocks of no more than ten minutes. I can watch one block and then catch another block later if I'm too busy to watch the entire episode in one sitting.
I don't know who decided on this format but I think it was an excellent idea! I find that when a friend e-mails me a youtube clip that's longer than fifteen minutes, I tend to put off watching it until later...sometimes not at all!
