The next Google?

Tonight I watched this segment on 60 minutes that I had recorded on my DVR from Sunday night. I thought it was interesting to hear how analyists are saying the Facebook is the next Google. I wondered if they were going to compare Facebook and MySpace and their differences. I know the Facebook is huge at Harding and MySpace is blocked under the category social/dating. While the interview talked a little about the technology involved, it really focuses on the business aspects of Facebook and the worth of the company. How will Facebook make money? Is it really worth the estimated 15 Billion dollars? I guess only time will tell.
