Imagine for example that on the Chrome home page, where sites you visit often appear, Chrome also was following the RSS of these sites in the background, and listing new news items for those sites on the home page, all without you having to do anything.
There is infinite possibility here for browser vendors to make browsing quicker, easier and more intelligent and RSS is a key part of that. The browser vendors are not interested in exploring this avenue and as such everybody is stuck doing the same stupid routine every single day. This is dumb! Our computers should be smarter than this!
