I don't think this article is aimed at consumers, but at developers who might have to write parsers, or people who are trying to decide what feed format to use for their own content. Though you might be upset about RSS being used when your reader screws up with it, because some things are difficult to interpret. Of course, you won't know why it screws up, and you'll probably blame the person who wrote the feed, not the format itself.
