Twitter have made it what it is today, and on its fifth birthday -- the company published a new video embedded below, featuring numerous celebrities explaining how and why they use the service. Richard Branson, Serena Williams, Piers Morgan, Snoop Dogg, Hillary Clinton and a host of others appear in the video to explain who they follow and how and why they use Twitter.
The company is also, a new website, blog posts, and has a national TV appearance on tap, too.
Finally, if you're more interested in the tech side of Twitter's five years, a blog post on the company's engineering blog explains how Twitter was "moved" twice last year to make the service more stable:
