Making the leap from normal TV to internet TV means you lose the ability to just turn it on. In order to watch something on Hulu, even in the background, I have to search, sort, browse and select through thousands of choices. Do I want to watch a new episode of 30 Rock? Or maybe an old episode of He-man? It takes way too much thinking!
Put in your Hulu username, and Random Reruns will randomly serve up a show from your list of subscriptions. I love anything that injects a little more randomness into the media diet.
