What is Twitter?
Twitter is a social networking and microblogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on the author’s profile page and delivered to the author’s subscribers who are known as followers. Senders can restrict delivery to those in their circle of friends or, by default, allow open access.
The use of Twitter’s application programming interface for sending and receiving text messages by other applications such as Tweetie often eclipses direct use of Twitter.
Since its creation in 2006 by Jack Dorsey, Twitter has gained notability and popularity worldwide.
Here are some stats on the use of Twitter worldwide and the implications of these stats to Twitter’s future.
