Twitter is a service for friends, family, and co–workers to communicate and stay connected through the exchange of quick, frequent messages. People write short updates, often called "Tweets" of 140 characters or fewer. These messages are posted to your profile or your blog, sent to your followers, and are searchable on Twitter search.
All you need to use Twitter is an internet connection or a mobile phone. Join us here! Once you're in, type your first update into the web box. To get an idea of what other people are saying or doing on Twitter, check out Twitter search to see what Twitter's all about. You can search by keyword or just check out the trending topics to see what's hot on Twitter right now.
When you create an account, you can search for people by name or user name, import friends from other networks, or invite friends via email. If you don't want to do that, follow some of the people we've suggested. Once you've found your friends, follow them to start getting their updates.
Following someone simply means receiving their Twitter updates. When you follow someone, every time they post a new message, it will appear on your Twitter home page. New messages are added to your home page as people post them, so you always get the updates in real time. When you log in, you can see what the latest updates are. Twitter offers other ways to follow people too: you can get updates from certain people on your phone!
After you click the follow button on someone's profile, you're following them. The follow button will change to a green check mark next to the word "Following" with an actions button on the right to remove a person if you want to. If you've registered your phone with Twitter, you can set up text preferences for a person as well. See a list of people you're following by clicking on the following link on your profile or your home page's sidebar.
Twitter sends you an email when someone new follows you. Set up your email preferences to notify you when you have a new follower. The followers link on your profile page or home page's sidebar will also tell you how many followers you have.
Twitter recently added follow and update limits for stability and abuse control. You can read more about this here.
It's up to you. Your followers read your updates, and anyone else who comes across them in a search. Your Twitter profile is public by default; if you're hesitant to have strangers read your updates, protect your profile to approve followers and keep your updates out of search.
Yes, you can. If you block someone, they won't be able to follow you or send you any messages. If your account is public, they'll still be able to view it, but they won't show up on your followers list, and you won't be on their following list. If it's a spammer you're blocking, thanks! Twitter Support keeps an eye on block reports to see who's getting in trouble on Twitter.
Twitter offers many ways to post updates: from the web in the update box, from your phone, from your mobile web browser using m.twitter.com, or from any third party application made by the talented folks who've utilized our API.
The star is a way for you to mark an update as favorite. People can view your favorites, and you theirs, by clicking on the Favorites link in the profile page.
Yep! Put a Twitter widget on your blog, website, MySpace... anything that accepts Javascript or HTML. You can even customize your Twitter badge to match!
An @reply is a public message sent from one person to another, distinguished from normal updates by the @username prefix. If a message begins with @username, we collect it as a reply. Reply publicly to any update on Twitter by using the @username format. Following is not necessary to reply to someone, and all of your replies are visible in the @username tab in your home page sidebar. (Tweets with @username elsewhere in the tweet are also collected in your sidebar tab; tweets starting with @username are replies, and tweets with @username elsewhere are considered mentions.) Please note that if your account is private, users who are not following you will not see your @replies or mentions.
Direct messages are private messages sent from one Twitter person to another. You can only send a direct message to a person who follows you. When you receive a direct message, we save it in your direct message inbox, accessible from the Direct Message tab in the sidebar in your home page. Set your email preferences to notify you by mail if you have a new message.
Nope. Once it's out there, you can't edit it. You can delete an update by clicking the trash icon on the right end of the update, but you can't make changes.
An @reply is a public message sent regardless of follow-ship that anyone can view. A direct message can only be sent by someone you follow, and is a private message that only the author and recipient can view.
RT is short for retweet, and indicates a re-posting of someone else's tweet. This isn't an official Twitter command or feature, but people add RT somewhere in a tweet to indicate that part of their tweet includes something they're re-posting from another person's tweet, sometimes with a comment of their own.Check out this great article on re-tweeting, written by a fellow Twitter user, @ruhanirabin.
The good news is they're not lost or gone! We have all your tweets. The bad news is that we currently only allow you to see the 3200 most recent tweets (this could also be construed as good news, as that number could be lower than 3200). The other good news is that we are eventually going to build something that will allow you to see ALL your tweets. Among the gazillion things we want to do to make Twitter better, this hasn't yet reached the top of our list, which is largely based on what we hear from people like you. At some point, you'll be able to get on a twime machine, visit your twistory, and tweminisce. That will be a fun day!
Twitter doesn't offer an official picture posting feature of its own, however, most people use a third party application (a popular one is TwitPic) to post pictures to Twitter accounts. Check out other photo and video apps on the Twitter Fan Wiki here! Note: Twitter doesn't officially support Twitpic or other third party applications, but you can usually find them on Twitter (follow TwitPic here) to get help or find out the latest updates!
The @replies RSS feed requires authentication; most web-based feed readers don't support authentication. If yours doesn't, you won't be able to see your @replies via rss feed. Try the feed in a desktop feed reader, which usually supports authentication.

No. We escape all html for security purposes. However, if you paste in a link that is less than 30 characters, we'll post it in its entirety. If it's longer than 30 characters, we'll convert it to a shorter URL.
