Twitter is a web platform that offers a lot of news online, where people communicate in short messages called tweets. Tweeting is posting short messages to anyone who follows you on Twitter, in the hope that your messages will be useful and interesting to someone in your audience.

Some people use Twitter to discover interesting people and companies online, opting to follow their tweets. Status updates can be made through the website, via SMS, instant messaging programs, email, or through various applications based on the Twitter API.

Registration in Twitter: Log in to your home page and click on the "SUBSCRIBE" button in the right-hand column. Fill in the form that opens with the following information: user name, password and e-mail address. Then click on the "I accept" button, then "Create my account".

How to publish in Twitter: After registration, open the homepage of Twitter thanks to which we can publish our twit. Write something in the text field: What are you doing? And click on the Update button to post it. Each twit can have a maximum length of 140 characters. The twit can also be useful to report funny websites or anything there to your mind. It is customary to use twit in the third person singular. You’re doing something and you want to let everyone know? Just write it on your profile. The twits that are sent are published in your personal page that is visible to anyone who can log in your space on Twitter.

How to use it: You can tweet about what you're doing, but if you're going to use Twitter mostly on a personal level, you'll have to share valuable content for your followers.

You can also join conversations. You can send a public response to people by putting @ before their username and typing your message. You don't even need that person to follow you or you follow them. Yes, your response is also public; any Twitter user can see it.

If you want to send a message to someone privately, you can also do it, but for that reciprocity is necessary, you both have to follow each other.

If you want to share with your followers a brilliant content or message from any Twitter user, simply "Retweet" by clicking on a button below each message with the name "Retweet" when passing the mouse over any message.

You can save a message to read it later or simply to save it, leaving it marked as a "Favourite" by clicking on the star that appears when you put your cursor over any message.

Through trending topics and hashtags we can follow the conversations on specific topics that people on Twitter are commenting on. It's like entering a restaurant where each table has a "hashtag" that indicates what you're talking about and you can listen to the conversations and converse at any time. You may have seen it on television: on the screen appears a word or phrase preceded by the sign "#" pad: that is a hashtag.
