The best listing of online newspaper from the whole world is at theInternet Public Library
As far as my own list of favorite news sources is concerned, there is nothing very original, I'm afraid:
CNN - hard to ignore
BBC - reliable old Beeb is strong in cyberspace too
Washington Post - the view from inside the Beltway
(For comments - rather than news - from a slightly different angle check out Salon Magazine)
Take a look at my links to radio sites as well.
