Oral tradition and the blog phenomena

I have written a sermon for Sunday which focuses on the way that oral tradition preceeded the written record. Not so boring as it might seem I hope. But the thing that strikes me is that the phenomena of blogging as it affects culture today through technology and the internet might have parallels. Although bloggind depends on putting thoughts down in writing the medium is one that allows for interaction and for the development of traditions and history in a fluid sense. The aspect of telling people's storys and relating their on going experiences so that they will be kept. The lack of dependance on the third party but the direct access to the narrative and the experience told. If I speak the story it has a potential to be absorbed in the universe without ever impacting anyone as much as the blog can be read and remembered by many, few or no one but me.
