Twitter is an information network made up of 140-character messages called Tweets. It's an easy way to discover the latest news related to subjects you care about.
Twitter contains information you will find valuable. Messages from users you choose to follow will show up on your home page for you to read. It’s like being delivered a newspaper whose headlines you’ll always find interesting – you can discover news as it’s happening, learn more about topics that are important to you, and get the inside scoop in real time.
If you remember one thing after perusing this post, it should be this: reading Tweets and discovering new information whenever you check in on your Twitter timeline is where you’ll find the most value on Twitter. Some people find it useful to contribute their own Tweets, but the real magic of Twitter lies in absorbing real-time information that matters to you.
