Feeds for genre writers - link soup

As a genre writer (I write science fiction, fantasy, and horror, so I can't pin it down much closer than that), I follow a number of feeds that are helpful. These fall into three main categories: excellent genre fiction, markets/writing how-to, and science/futurism.
