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 :)
