text: User engagement User engagement is usually measured by the number of likes, replies and reposts. A 2023 study showed that retweets are more likely to contain positive content and address larger audiences using the first-person pronoun "we". Replies, on the other hand, are more likely to contain negative content and address individuals using the second-person pronoun "you" and the third-person pronouns "he" or "she". While influencers with many followers tend to post positive messages, often using the word "love" when addressing larger audiences, users with less followers tend to engage in interpersonal conversations to provoke user engagement.
  Branding
  When it was known as Twitter, X was internationally identifiable by its signature bird logo, or the Twitter Bird. The original logo, which was simply the word Twitter, was in use from its launch in March 2006. It was accompanied by an image of a bird which was later discovered to be a piece of clip art created by the British graphic designer Simon Oxley. A new logo had to be redesigned by founder Biz Stone with help from designer Philip Pascuzzo, which resulted in a more cartoon-like bird in 2009. This version had been named "Larry the Bird" after Larry Bird of the NBA's Boston Celtics fame.
