I've updated the RSS 1.0 feed template. I should probably have done this years ago, but you know how these things go. It now includes much more metadata, and in particular should correctly transmit formatting, images, and the like.
Of course, nobody accesses the RSS 1.0 feed directly. However, it is the base data source for the LiveJournal feed version of EGAD, so this actually impacts a number of readers. Feedback, particularly from these people, is appreciated.
