How the "first draft of history" gets written has changed a lot in my adult lifetime.
It used to be said when I was a lad that journalism was the "first draft of history," and that conceit helped draw me into writing for The Daily Texan in college. There I learned, in fact, that the press release was the first draft of history, but even that has changed. After a while the "first draft" began to show up on blogs, and today, more often than not, it comes in a blog comment.
I'm not sure whether I think that's good or bad, but I think it's true.
It's also been said that winners write the history, but to a large extent, that has changed, too. If there's one thing you can say for the blogosphere, it's that it's definitely given losers a voice!
