According to this online article, blogging is a simple process of publishing and distribution of words. Anyone with internet can share their thoughts with the world within seconds and at virtually no cost. The blogsphere draws on a wider range of media, spanning text, image, audio, video and software applications. As a consequence, media is becoming more and more open, collaborative and participatory.
