Since Google introduced real-time search last December, the search engine has added content from MySpace, Facebook and Buzz to live updates on popular sites like Twitter and FriendFeed, as well as headlines from news and blog posts published just seconds before. Today, the Official Google Blog introduced a new feature to help you search and explore the public archive of tweets.

Get it? Got it? Good.
Casey added, "By replaying tweets, you can explore any topic that people have discussed on Twitter. Want to know how the news broke about health care legislation in Congress, what people were saying about Justice Paul Stevens' retirement or what people were tweeting during your own marathon run? These are the kinds of things you can explore with the new updates mode."
He said that the replay feature is rolling out now and will be available globally in English within the next couple days. If you want to try it now, click on this special link to see the relative volume of activity on Twitter about Obama.
Initially, you can explore tweets going back to February 11, 2010, but soon you'll be able to go back as far as the very first tweet on March 21, 2006.
Is that cool or what?
