The fastest, simplest way to stay close to everything you care about.
An information network
Twitter is a real-time information network that connects you to the latest stories, ideas, opinions and news about what you find interesting. Simply find the accounts you find most compelling and follow the conversations.
At the heart of Twitter are small bursts of information called Tweets. Each Tweet is 140 characters long, but don't let the small size fool you—you can discover a lot in a little space. You can see photos, videos and conversations directly in Tweets to get the whole story at a glance, and all in one place. See it in action.
You don't have to tweet to get value from Twitter
You don't have to build a web page to surf the web, and you don't have to tweet to enjoy Twitter. Whether you tweet 100 times a day or never, you still have access to the voices and information surrounding all that interests you. You can contribute, or just listen in and retrieve up-to-the-second information. Visit fly.twitter.com to learn more about what's yours to discover.
Twitter around the world
Twitter was founded in San Francisco, but it's used by people in nearly every country in the world. The service is available in more than 20 languages, and we continue to add them. You can change your language preference in your user settings with just a few clicks.
Twitter on the go
Experience Twitter on your mobile device by using one of our free Twitter apps for iPhone, iPad, Android, BlackBerry and Windows 7. To get the latest apps, go to twitter.com/download on your mobile device.
Twitter for SMS
Twitter for SMS is an instant infrastructure for mobile communications. Individuals, businesses and social causes can use Twitter for SMS and our Fast Follow program to connect directly to anyone with a mobile phone. Here's a list of all the countries that offer Twitter for SMS; we are actively working to add even more.
Twitter in the Community
Twitter lends itself to cause and action. Every day, we are inspired by stories of people using Twitter to help make the world a better place in unexpected ways. Visit stories.twitter.com to learn more.
And with just a Tweet, millions of people learn about or show their support for positive initiatives that might have otherwise gone unnoticed. Programs like Twitter Ads for Good offer a way for non-profit organizations to promote their efforts the same way as businesses can. As more community-centric organizations join the platform, citizens will increasingly engage with the efforts taking place to move their community forward. Follow @TwitterGood and @TwitterSF for more on these topics.

I would not feel completely confident using this tool with a class and would not use it for students to follow me yet as there are some drawbacks. I sometimes get messages to follow some dubious people. I ignore them and the message has usually been deleted within a few hours. Also, a disgruntled student could write anything they like, which can be worrying.
Overall, a great way to network and find inspiration. I would recommend other teachers follow other teachers.
Twitter can also be used by educators in the classroom by sending messages (also known as "tweets") about homework assignments or what may be going on the class on any given day. Students are then able to "follow" their teacher's tweets and avoid risking missing assignments. I recommend Twitter as a fun, casual way for teachers to communicate with their students.
