MySpace gave users a lot of freedom. That was great in certain scenarios but at it got bigger it meant there was just more noise and the general atmosphere was very messy for lack of a better word. Facebook was very clean by comparison and it felt natural to connect to people who couldn't handle MySpace, people in your family or at work etc. Then eventually it got big enough through that that it just became the place to connect with your cool friends too because "everyone" was there.

So yeah, it's kinda mixed. The core product was cool but it wasn't as suitable for as a replacement for the phone book in the way Facebook was.

...but most of all, Samy is my hero!
