I have the opposite problem. I started writing content, then started writing custom markup to convert the content to HTML. But I started having so much fun writing marked-up content, it took over. So I have a content surplus. I know from past experience (personal and that of others) that getting content online is fairly easy. The part I don't get is how to find an audience for content that 'is good' - but doesn't have broad appeal. Publishers know that stuff, who else does?
