What is Twitter?
Twitter is a service for friends, family, and coworkers to communicate and stay connected through the exchange of quick, frequent messages. People post Tweets, which may contain photos, videos, links and up to 140 characters of text. These messages are posted to your profile, sent to your followers, and are searchable on Twitter search.

What's a Tweet?
A Tweet is any message posted to Twitter which may contain photos, videos, links and up to 140 characters of text. Click or tap the Tweet button to post the update to your profile. Read our Posting a Tweet article for more information.
Following someone means you've chosen to subscribe to their Twitter updates. When you follow someone, every time they post a new message, it will appear on your Twitter Home timeline.
After you click or tap the Follow button on someone's profile, you're following them. See a list of people you're following by clicking on the following link on your profile page or on your home page's sidebar.
Twitter sends you a notification when someone new follows you. Set up your email preferences and mobile push notifications to notify you when you have a new follower. The Followers link on your profile page will also tell you who is following you.
Twitter has follow and update limits for stability and abuse control. You can read more about this here.
Your followers read your Tweets. If your Tweets are public, anyone who runs a search for a keyword in your Tweet may be able to see that message. Your Tweets are public by default; if you're hesitant to have people you may not know read your updates, protect your Tweets to approve followers and keep your updates out of search.
Read our article about how to post a Tweet. You can Tweet from twitter.com, a mobile device, or an application.
A reply is a response to another person’s Tweet. Click or tap the reply icon on another person's Tweet to reply to it. Please note that if your Tweets are protected, people who are not following you will not see your replies or mentions.
Direct Messages are private messages sent from one Twitter account to other Twitter account(s), and they do not appear in public for anyone else to read. You can start a conversation with anyone who follows you.
What is the difference between a reply and a Direct Message?
A reply is a public message sent regardless of follow-ship. Anyone can view it (if your Tweets are public). A Direct Message is a private message, and can only be seen by the sender and intended recipients.
No, you can’t edit a Tweet once you have posted it, but you can delete it.
A Retweet is a Tweet that you forward to your followers.
