Changing Headlines

Watching headlines change on the New York Times home page can be pretty revealing. Unfortunately, the Times doesn't provide a mechanism for readers to track changes to headlines or articles (at least not that I know of). Here's an interesting modification that I caught today. A couple hours ago, the headline for this article was something to the effect of "Google Acquired YouTube for $1.6B." The headline now reads "Google Is Said to Set Sights on YouTube." Perhaps the editors were a little too quick to pull the trigger? There's nothing like getting the scoop, is there?
