It's hard to believe that Twitter [1] is now 10 years old. The social network didn't truly break into the mainstream until a few years after launching, and its evolution has been fascinating [2] to watch. These days, Twitter is a resource for breaking news, a platform for authors and writers to chronicle their lives, and the place where we go to find memes. Celebrities love to tweet because it allows them to connect with their fans and speak authentically (maybe too candidly sometimes [3]). Twitter has released an interactive feature [4] that allows you to see how some of its most popular tweets traversed the world in seconds. In honor of a decade of Tweets, we've compiled a highlight reel of Twitter's best since its birth in 2006.
