Makes sense put like that. Explains why Myspace died down but never truly died too. It doesn't make too much sense that Facebook has been hanging around so long though with all the shit they've dealt with.

Facebook is powered by my 50+ year old relatives and my 30+ year old single mother classmates. They don't really know how to use the Internet besides Facebook and Youtube so they have nowhere else to go. 
  
 Myspace was still in the time a decent amount of people knew how to use the general Internet and there was a balance of power users and casual users.
