With half a billion free account holders, Twitter is one of the top 10 most visited websites on the internet. The social networking service and micro-blogging site has been running for six years now and is the place to go to find out the latest news as well as chatting with friends and sharing photos.
Twitter is easy to use when you know how
Many people still don't understand what Twitter's all about though, and don't see the need for any other social networks beyond Facebook. Here, we'll explain exactly what Twitter is, why you might want to use it and how to set up an account and start tweeting. See all social network 'how to' articles
Twitter is essentially a collection of short text messages called tweets. They're similar to Facebook's old status updates which told friends and family what you were doing or feeling right now.
Although many people use Twitter for exactly this purpose, you can also share links to online article or videos you like, or attach a photo to a tweet for people to view. You can also share your location with a tweet so people know where you are.
Tweets can be up to 140 characters long, which means you have to be concise in order to get your message across.
You can read people's tweets if you visit the website, but you can write a tweet only if you sign up for a free account.
Tweets are public so anyone can read them, but you can send a DM (direct message) to someone who 'follows' you. A DM is a private message which only the recipient can view.
Any Twitter user can follow you - you can't prevent this. Following you means any tweets you write will appear in that person's timeline (like Facebook's News Feed). Similarly you can follow as many people as you want, and their tweets will appear in your timeline.
Search and trends
Twitter is a great place to find like-minded people, and it's also a much better place than Facebook to get close to celebrities. Unlike Facebook, celebrities tend to manage their own Twitter accounts, so you get more up-to-date news about what they're up to and a better insight into what makes them tick.
To find someone, just type their name into the search box. Results are divided into people and tweets, and you can toggle between the two by clicking the menu on the left side of the page. You should be able to tell if you've found the right person by their photo and short biography.
You can use the same search box to find tweets. Twitter uses hashtags to mark keywords in a tweet. You'll often see these at the start of TV programmes, such as #bbcqt for Question Time. Entering that exact hashtag into Twitter's search box will return a list of tweets containing it so you can see what people are saying about it.
Similarly, if you want to ensure other people see your tweet about the programme, you should include #bbcqt in your tweet. You can make up your own hashtags, but it's best to use words that people will search for.
