Analysis: It will be interesting to see if YouTube can sustain its exponential growth. I looked on Alexa and it has MySpace at No.6 and YouTube at No.9. I’m not sure YouTube will overtake MySpace. MySpace is a much different site — more about people creating their own social pages — that has a lot of attraction for all kinds of people, especially young teenagers. The video file sharing space probably has a more limited audience, at least right now.
