This article from eMarketer shows that social networking usage has nearly doubled in the last two years. As a relative newcomer to social networking, it is easy to see some of the great things about it: it is easy to reconnect with old friends, share events and photos and simply stay more connected. I wonder if these college students are spending more time online (ie. twice as much) or if they are spending less time doing other things online and now mostly just social networking? Your thoughts?
