The RSS link was quite amusing. My Chrome instance downloaded the RSS file without displaying it. Then I clicked it to open, and it opened Firefox. Firefox showed its file download box, suggesting I open the RSS with Google Chrome.
On Linux, right? Firefox, or whatever gnome/dbus/opendesktop/gtk fuckery it uses has all sorts of strange notions about file types. When I download a tar.gz file, it saves a copy to /tmp, then launches a new instance of firefox with a file:// url, which opens a save file dialog.
AFAIK Chrome has never detected RSS correctly for me. I assumed this was special to Mozilla, with their "we should probably provide a basic version of everything - newsreader, FTP client, etc., even if it makes the browser a bit more bloated." Bit like emacs.
Chrome is a bit like vi, if you want more stuff, there's probably some sort of extension.
Sorry for the emacs/vi analogies, I'm not trying to flame :)
