I'm not sure if anybody else is using both ForceField and Brief, but when ForceField/virtualization is enabled, Brief displays the feeds without any formatting whatsoever. I also use Sage-Too which uses a locally stored CSS file, but for some reason ForceField conflicts with Brief's rendering of feeds.
