google-readerrss
I'm sure some people really love that new feature, but I use Google Reader so it's driving me batty. Not to mention that as a tech guy, I might want to actually view an XML feed once in a while (like for instance, Sparkle update feeds).
So how do I stop Safari from redirecting the normal XML feeds to their "feed://" pseudo-protocol?
The feed URL can only be edited if Google Reader sync is off.
Select the feed in the left column and press ⌘I to bring up the feed info window. Click on the triangle next to the URLs entry and you will get a text box that will allow you to edit the feed URL. There are a bunch of other setting there that allow you to do things like specify how often a particular feed is updated, how long articles are kept, etc.

Apparently, it used to be possible in Tiger/Safari 2.0 to disable this using
defaults write com.apple.Safari DebugSyndicationEnabled -bool NO. (source) I cannot get this to work in Lion/Safari 5.1, however.Your best bet seems to be to set the default feed reader (Safari → Preferences… → RSS) to something that gives you XML source.
