Well, this isn't really about using the tool wrong. Because, using it right means that there's something about the tool which you're not aware of. That's never a case with knowledge/information consumption. There are as many different ways of consuming information as there are a number of people. When it comes to a platform (RSS in this example) the perspective shift is the only thing you can do. You can have a single source of information and still end up with 1000 unread items.
