It’s very hard for people to agree on something. RSS happens to be one of these things. More and more tools and services will come out to leverage this universally agreed format. And people will use it more and more. At this point, people are only use RSS at the high level. But later, they will digg into one level lower: to figure out RSS structure. Anyway, it’s not difficult to understand the concept of channel and item. It’s so natural to people watching TV.
