Twitter, Growing Up On Its 7th Birthday, Hints At Its Politics

Thursday is Twitter's seventh birthday, which is like 100 in Internet years. It all started on March 21, 2006, when Twitter co-founder Jack Dorsey sent his first tweet, which read "just setting up my twttr" (without vowels, as the service's name was written originally). Over the course of a few short years, Twitter grew into the social and news behemoth. Twitter has an estimated 200 million active users in 2013.

To celebrate its seventh birthday, Twitter has released a video chronicling the site's history. And all grown up, Twitter subtly reveals political inclinations by including quite a few liberal-leaning moments in Twitter history. For example, the video mentions the Egyptian revolution of 2011 and the most retweeted post of all time, which was a photo of President Obama hugging the First Lady with the caption "Four more years," as significant moments in the company's history.

It's certainly not shocking that Twitter highlights such moments. The website's users skew slightly to the political left, according to a recent Pew study. And Silicon Valley, which Twitter and most of its employees call home, was overwhelmingly Democratic in the 2012 election.

Politics aside, we thought it would be fun to look back at the first nine Twitter users. No convoluted Twitter handles here! Check them out below:
