Beyond entertainment, what is the purpose of these writings? How do they function/fit into our culture?

We all have freedom of expression. We have the ability to express our feelings and ideas in many different ways, and writing in a blog happens to be one of those ways. I noticed that in todays society, well...the new generation has a problem with expressing themselves vocally and the purpose of these writings is to help express ourselves with what we know best, messages or in other words...text. Writing in blogs fit into our culture by a way of learning. there is a saying "you learn new things everyday" and writing in blogs can also help us learn new things about ourselves and reading the writings of others help us to learn new things about other people...
