hmmm... arent there already such sites like MySpace etc.
Well myspace was the top dog, facebook took over and myspace is fading away, the same could happen to facebook, and quite quickly if the right people get together and find the right funding.
I'm not saying it will be easy to knock over facebook but it is much more vulnerable than someone like google as facebook stands at the moment.
That said, facebook is in a good position to take on google, and maybe that's why they're willing to invest, we don't know what's going on behind the scenes.
