text: A few days after the rebrand took effect, an AP Stylebook update recommended that journalists refer to the platform as "X, formerly known as Twitter". In September 2023, Ad Age, citing The Harris Poll, noted that the rebranding had not publicly caught on, with the majority of users as well as notable brands still referring to X as "Twitter". In December 2023, Fidelity estimated the value of the company to be down 71.5 percent from its purchase price. However, the purchase occurred just before a marketwide price drop and Musk acknowledged that he overpaid for the service. Since Musk's takeover, data from app-tracking firms has shown that global usage of X has declined by approximately 15%, compared to a decline of 5–10% in some other social media sites. This decline in usership has been disputed by Musk, who claimed in May 2024 that there were 600 million monthly active users and 300 million daily active users.
  On May 17, 2024, the URL was officially changed from twitter.com to x.com.
  Appearance and features
  Tweets
  Tweets were publicly visible by default, but senders can restrict message delivery to only their followers. Users can mute users they do not wish to interact with, block accounts from viewing their posts, and remove accounts from their followers list. Users can post via the Twitter website, compatible external applications (such as for smartphones), or by Short Message Service (SMS) available in certain countries. Users may subscribe to other users' posts—this is known as "following" and subscribers are known as "followers" or "tweeps", a portmanteau of Twitter and peeps. Individual posts can be forwarded by other users to their own feed, a process known as a "repost" or "retweet". In 2015, Twitter launched "quote tweet" (originally called "retweet with comment"), a feature that allows users to add a comment to their post, imbedding one post in the other. Users can also "like" (formerly "favorite") individual tweets.
