Mood blogging. By analogy: in the beginning was the Web page, and it was long;
then came the blog post, and it was shorter; then came Tumblr, and it was
shorter yet; then Twitter, and it was down to 140 characters.
The next progression is a symbol. In this case, an emotion or mood represented
by an image or emoticon.
That is moodswings. This is the future.
