When Martin Luther nailed his theses to the door of Wittenburg Church, it was the beginning of religious reformation. Today, with the proliferation of blogs, especially by elected officials, we are seeing a new sort of reformation, a political reformation.
Most theologians mark the Protestant Reformation as the time in which the masses were able to have access to the Bible in a way that they could understand it. The Bible, which is referred to by Christians as "the Truth" has many parallels with blogging. Consider the change of mainstream media in the United States, which has unmistakably and undeniably trended toward sensationalism. In the process, much the truth has been lost. Many politicians have adapted to this trend and sought to guard their own intentions and perspectives in the hope to appeal to the superficialism that has captured American media.
This lack of authenticity, I believe, has also been a major cause of dissatisfaction with government and politicians. People yearn for authenticity, they want to know that when a politician says something it is hasn't gone through hundreds of edits and screened by a public relations firm. Blogging by virtue of its rawness can serve as the direct link between constituents and their elected officials. With a blog, you get to hear it from the horse's mouth. Sometimes what you read on a blog may rub you the wrong way. This, ultimately is the double-edged sword of blogging. However, for a blog to maintain its value, it must be unscripted, unrehearsed and real. This "realness" is what makes a blog, a blog. It is the new horizon in which the truth, from the perspective of the author is only a few keystrokes a way. In short, blogging is the political reformation.
