This site hosts feeds of all forums and blogs that are being scraped and aggregated by the Ermarian Network.
These forums may be aggregated some time in the future: Polaris, the Lyceum, Desperance.
I am also looking into the API of Google Co-op which may allow me to offer several SW/endeavor-related feed-based services that can seamlessly integrate into your Google interface. This may take a long while yet.
The popular blog Baghdad Burning is scraped by this site because the built-in atom feed provided by Blogger is either disabled or broken. The feed has a refresh rate of 30 minutes and is fully valid RSS 2.0.
