> I remember Youtube back in 2005 when I was a freshman in HS. To be fair, most will remember being introduced to it in that year. Youtube became a household name in 2005 after the Lazy Sunday video, with much fanfare, was published on the service and it became essentially the defacto place to watch it. I'm inclined to believe that productions by kids maintained the interest in the service beyond that point, but it was content produced by adults that popularized it in the first place. With possibly the exception of Facebook, I think you could say the same about most social networking services. Twitter only became interesting to the general public after adult celebrities started contributing. Myspace was popularized by adults promoting their musical groups. > What is Facebook lacking? A monopoly on photo sharing. Anyone who can take that traffic away increases the risks of taking people away from Facebook completely, and that is a huge risk for them. The insane valuations for these companies (Snapchat, Instagram, etc.) are cheap compared to having everyone leave Facebook for another service.
