Moderation Squared

A little while ago I wrote about my general philosophy on life, which is simply : all things in moderation, including moderation itself. That post somewhat got away from me, so this time I'd like to focus more on the actual philosophy. Since my last post was all about why extreme positions are popular, I want to make the strongest, most violent case I possibly can for the virtues of being moderate. Yeah, I like irony. If being extreme is more popular than being a moderate, what about being extremely moderate ?
