No offence, but you're not getting this. The code is what the rss feed really looks like (as I said above). You aren't supposed to look at in a browser, you're supposed to look at it in a feedreader (like Google Reader).
As it happens, newer browsers such as Firefox 2.0 and IE7 (but NOT IE6) have built in feed viewers so that you see a feedreader-like view instead of the code.
IE6 doesn't have this, so you see the feed itself. The feed is exactly the same in both cases. Hope this make sense.
