If you're old enough to remember using MySpace in its prime, you're probably also familiar with the early YouTube sensation of Lonelygirl15. It started off exactly 10 years ago as just an everyday teenager speaking into webcam in a simple format that become known as the "vlog." This was long before everyone knew what "web series" or "going viral" meant. It went on to be revealed as a scripted series, and still survived for two years before fizzling out. But now it's back, with Lonelygirl15 posting her first video in eight years.
