I'm surprised to see how young deviantART users are considering the quality of its content. Since 2006, this site has been my goto location for anything graphic-related: drawings, web designs, pictures, Photoshop brushes and actions... Maybe 0-24 years old is the period when you're the most creative?<p>About Facebook: it's a website where you <i>build</i> your network, especially with family and close friends. Although I don't visit it anymore, I know my friends and family use it solely to follow each other's lives ('What have you been up to?'), while sharing theirs as well. It's not a one-time visit. You follow the evolution of your relations' lives, especially the major events of a lifetime: marriage and children. Facebook is the network where people go to develop and share their <i>real</i> identity (whether it's a good decision or not). The more you use it, the more you feel connected to it (and compelled to make a contribution). That's why most Facebook users who joined it at the age of 25-35 are now in their mid-life, because Facebook is the only online network they're part of.
