C-SPAN: A discussion (RealVideo) at the Library of Congress on the Digital Future, specifically 'blogging. If the RealVideo link doesn't work, check that your Real Player is set to play Real Time Streaming Protocol under Tools->Preferences->Media Types->Advanced. I know I had to manually check that box on mine after weeks of not being able to watch any C-SPAN video online. Nice one Real.
