One of the reasons RSS is catching on is the rise of blogs. As they proliferate, and do they ever, it becomes more difficult to find, visit, and keep up with the stream of monological consciousness; that’s about the most generous way I can describe blogs. What RSS brings to the stream (more like a tsunami) is the ability to sign on only with blogs that interest you, and then sort through the updated entries. Many people now using RSS got into it through blogs that offer it.
In general, I think the author kind of misses the point, primarily because he doesn’t blog or really understand what keeping a Web log means. This is still one of the first RSS magazine articles I’ve seen out there.
