RGE - Nouriel Roubini's Global EconoMonitor and the community of economic bloggers that it aggregates provides a rich source of thoughtful debate about the economy. For example, in Noriel Roubini's EconoMonitor there are links to posts about the Brazilian economy, the global credit crisis, whether there is a bubble in oil prices. I like Nouriel Roubini because he is honest and his analysis of the recent turmoil in financial markets has been consistently gloomy, but accurate.
