I was referring only to the notes…they seem to have RSS and Atom.

As for the updates, do you have a second account? I’ve got one for a statue in college set up with an alternate uni e-mail address (it’s from back in the days when fake accounts were cool because any mug couldn’t just sign up). I can see imported notes on my news feed, but they’re only accessible to other people if they visit your profile, whereas posted items, or Facebook-brand notes, make the person appear on your recently update friends list.
