Atrios looks back at his archives in this post. Makes you wonder why few newspapers ever do pieces where they look back at what the newspaper was thinking at specific points in history. Easy-to-access blog archives might make it tougher for revisionist historians to make sweeping claims about the general mood of the country during specific periods. Statements about the Iraq War like, "Everybody thought Saddam Hussein had weapons of mass destruction" will become tougher to make as bloggers can point to posts they made back in the day to show that, indeed, there was significant controversy over that point. Even if the blogging movement does nothing else, it will at least give us a running record of opinions within the context of time. It's interesting to think about the potential value to people in the future.
