• The New York Observer has a look at this morning's PdF 2010 whistleblowers' panel with Daniel Ellsberg and a piped-in Julian Assange.
• Team Facebook launches a new hub for news and tips on how politicians are using the platform well.
• Team YouTube launches a new hub to help 2010 campaigners figure out how to use the platform well.
• The Sunlight Foundation launches TransparencyData.com, "a central source for federal lobbyist registrations, federal grants, and federal and state campaign contributions." A little help making sense of it here.
• Marc Ambinder pre-blogs his own fact-checking panel, and goes beyond it to explore the nature of journalistic epistemological humility.
• John Perry Barlow says of the Internet, "it's made it impossible to govern anything the size of the nation-state."
• Jane Hamsher has a go at the conference them of whether the Internet can fix politics.
• Ethan Zuckerman blogs the talk he would have given, on overcoming apathy through participation in the context of Equatorial Guinea.
• In non-conference news, the New York Times nabs both Nate Silver and his Five Thirty Eight. And Ben Smith wonders what they didn't mention Silver's self-stated political bent.
• And consensus is that this is the worst website that has ever existed.
