Good ‘Blog arguments are interesting because the participants are sophisticated enough to spare each other the usual faulty reasoning and informed enough not to quibble too much about the premises. Because of this, and because the ‘Blogoholics are less likely to be as simply tribal and cautious as politicians, debates on ‘Blog comments pages can, on occasion, be gripping. Most importantly, unlike those involved in the imminent presidential debates, the protagonists are invisible. If I had to give one piece of advice to Kerry now it would be this: “This is not a race or an exam; remember that you are in a popularity contest now.”
