RSS done right (in firefox 2)

I love the way the release candidate 1 of Firefox 2 handles a RSS feed.

I accidentally hit a RSS feed today and was pleasantly surprised by the user experience. There was an informational message at the top explaining it as a feed, along with a RSS subscription preference option and a nicely rendered (not just XML data) feed.

Here's a short 1.7Mb movie of what that looks like the second time you click on it (the top explanation goes away and you just see the RSS subscription preference).
