How it used to work: Click on an RSS feed you'd see XML.
So they obscured the XML, and showed you the headlines and descriptions and linked to the stories in the feed.
The problem with obscuring the XML is that you make it harder to understand, not easier. Why are there two ways to view the news, and why is one so plain and ugly and the other so flashy and distracting?
That's how I'd like RSS to work. Click the icon. See the code. Either you're interested or you hit the back button. You can report it as a bug. Developers are familiar with the idea of bugs that never get fixed. They're called features.
It's very important in the minimal blogging tool that when the user clicks on the XML icon, he or she actually sees the XML. That's how I, the designer of the software, insist that it work. The RSS is the main result of their work. Any confusion about that is confusion about the product itself. And if you're a curious technically-inclined person, RSS actually interesting to read, and quite easily understood. Much more interesting than the vanilla stuff the browser guys want to present. And by having it easily visible, designers are responsible for keeping it easily understood.
