Each medium has both advantaged and disadvatages. Blogs seem to be very good for thinking, for informal discussion and for spreading ideas quickly; but they seem to me to be pretty bad for producing polished, well though-out articles and storing such articles in an accessible way. There is little incentive to rewrite your blog posts in the light of discussion. Blog posts tend to disappear from view after a few days, or weeks at most.
Now it seems to me that it would be very useful if RPG theorists, after thinking about a subject and discussing it with each other, would write nicely structured, thorough articles about their conclusions; and if these were stored and made easily accessible at some central place. In fact, this seems to me more important than unifying all these theory blogs at one location.
So maybe we need an online journal of RPG theory? This would be a website that publishes thoughtful articles about RPG theory. It would encourage authors to first discuss the subject on blogs, so they can test their ideas and improve them. It would peer review articles, but probably in a rather informal way by the editors - the standard academic peer review process would be both impractical and pretentious, I think.
I am especially interested in your opinion about this. What do you think? Do we need an online journal of RPG theory, as an addition to the current proliferation of blogs?
