Jim Long & Andy Carvin Talk on Social Media and Journalism at Podcamp DC
It was a session that was packed. Both gentleman are very experienced and are world travelers and can say " The other day when I was at the White House" :).
They used a wiki http://andyjim.pbwiki.com/ to present and is rich with resource and example links.
They are great guys and are good friends. Instead of summing up their talk let me point you to some great posts written by other smart people.
