# Week 3 Social Networking - Facebook & Twitter

I'm on FB, and other social network sites, mainly to keep in touch with my friends, most of whom are scattered all over the world. It is a great tool for that purpose, definitely cheaper than phoning everyone. And since most of my friends post photos regularly, i can keep track of how fast their kids are growing up. I haven't signed up to Twitter, because personally i don't "jump" online enough to keep up with it.
