To celebrate Twitter's 8th birthday, I spearheaded an initiative to create a tool where anyone can enter their Twitter username to find the first message they ever Tweeted. In addition to the interactive experience (which went viral), a series of celebrity first Tweets were illustrated and Tweeted out via various Twitter corporate accounts (as well as Retweeted by those celebrities!) The sheer volume of Tweets using the #FirstTweets hashtag on launch day was in the hundreds of millions. The campaign received global press coverage and helped reemphasize the message that Twitter was the world’s public town hall - from celebrities to politicians, to everyday people alike.
