Why do some create blogs and why do others read them? This is actually a ten points question since its answer covers the very working principle behind the entire phenomenon. First of all, we are not far from the truth when saying that bloggers are very much like journalists or columnists, and that the material we find on blogs is very often much more interesting than that in the media thanks to the personal touch writers include in their articles. Furthermore we cannot ignore the interactive dimension of blogs, which is probably the greatest advantage in itself: comment boxes for instant responses, links to documented materials, videos and pictures turn the blog into a magic puzzle.
