Why do only my Twitter posts show up?

I have added Twitter, MySpace, FaceBook, and Pandora in My tools > Set up my lifestream. However only Twitters I've posted show up in my Lifestream (no other services), and nothing shows up in Friends' Lifestream (says I have no friends). When I go to My tools > Manage freinds' lifestreams, the main pane is blank, and to the right only Twitter shows up (no other services) and there is nothing I can click or select. It says:
twitter - Updates from me and my friends - included in your Friends' Lifestream. Why can't I see others' posts and services besides Twitter? I can see posts, status updates etc on the services themselves and on other social aggregate sites ok, so I know they are there.
Thanks.
