text: Twitter Spaces is a social audio feature that enables users to host or participate in a live-audio virtual environment called space for conversation. A maximum of 13 people are allowed onstage. The feature was initially limited to users with at least 600 followers, but since October 2021, any Twitter user can create a Space.
  In March 2020, Twitter began to test a stories feature known as "fleets" in some markets, which officially launched on November 17, 2020. Fleets could contain text and media, are only accessible for 24 hours after they are posted, and are accessed within the Twitter app; Twitter announced it would start implementing advertising into fleets in June 2021. Fleets were removed in August 2021; Twitter had intended for fleets to encourage more users to tweet regularly, but instead they were generally used by already-active users.

  Trending topics
  A word, phrase, or topic that is mentioned at a greater rate than others is said to be a "trending topic". A topic can "trend" because of an event that naturally prompts tweets, or through a concerted effort by users. These topics help Twitter and its users understand world events and the public's opinion on them. The Twitter web interface displays a list of trending topics on a sidebar on the home page, along with sponsored content.
