Terry Teachout has written a formidable essay on the brief history and broad culture of blogging. It's maybe the most considered statement yet on a phenomenon that has inspired a huge amount of breathless commentary, both of the effusive and panicky sort. Terry makes the point that blogs need not be seen as rivals to traditional media. The Internet has simply multiplied the media in which writing becomes available. No matter what the medium, only good writing will survive. Terry also celebrates the Internet's embrace of the older and more eccentric art forms, which most major media outlets now avoid like the plague. A case in point is the lively, expert opinion on the Van Cliburn blogs, official and unofficial. It's not surprising, in the end, that another brawny virtuoso (Alexander Kobrin) won the competition. It is surprising that a single post on a piano blog drew 113 intelligent comments.
