Twitter is a social media platform that allows users to post short messages called tweets. Tweets are limited to 140 characters. Users can follow other accounts to receive their tweets and have their tweets shared with their followers. While it started as a way to share what you're currently doing, Twitter is now used to share all types of real-time information and connect with others online. Some ways to benefit from Twitter include gaining followers, promoting your business or brand, and staying up to date on news and topics you care about.
