Twitter is a social media network which allows users to post short messages (“tweets”) of up to 280 characters. Tweets can consist of text, photos, videos, audio, links, polls and GIFs – often linked by hashtags if they share a common theme or message. Hashtags receiving high levels of interest are said to be ‘trending’. Twitter users can engage with other people’s posts by liking, retweeting (sharing) or tweeting back (commenting on). Since the entrepreneur Elon Musk acquired Twitter in October 2022 for $44 billion, he has implemented several major changes to the platform.
