Is literature on the Decline?

I personally disagree with Orwell's excerpt. While it is true students today are more inclined to shorten essays and have interest in them due to facebook and other blogging websites, I believe this is not such a bad thing. In the real world being able to communicate with others in a quick and precise manner is very important. In large essays, there is a tendency to fill in useless details in the interest of length, when it is really not an equal amount of worthwhile content. Orwell is saying literature is on the decline because of a lack of interest in depth, but I think we as a generation are simply defining depth in a different way. I feel like it used to be if an author wanted to express their opinion, they would write a book exhibiting it. Today, someone might, instead, simply write their opinion on a blog or on facebook. This is a big problem according to Orwell, but I don't think it is. It's possible we are just expressing our opinions in a different way than in the past allowing us to expand our knowledge in a much easier and faster way.
