For those coming in late, the "blogger ethics panel" joke is about how for years concern troll journalists tried to applied ethical norms and disclosure standards which didn't exist anywhere in the universe to bloggers. It was a neat trick replacing what was once called "establishment journalism" with the "liberal journalism" as those who catered to the existing power structure could pretend that they were fighting for the little guy.
The powerful have always had better access, now they've just printed the menu card.
