Another site that has hit, and passed, the tipping point. Justin.tv. From the site:
Justin wears the camera 24 hours a day, 7 days a week. Even in the bathroom. Even on a date.
So there it is. Being on justin.tv is a good thing. And as I type this, he has only been live for 19 days, 16 hours and 17 minutes. This will be big. Go Justin!
