Twitter is a social-networking Web 2.0 Application that allows its users to share any updates in a persons life to be shared with friends in 140 characters or less. Because of the limited amount of symbols you are allowed to use, it is also called a micro-blogging application. It was built using Ruby on Rails and as most Web 2.0 Applications its API can be used for mashups of any kind. Simular services are Plazes.com with the addition of a more in-depth profile and geo locating feature. Both applications built a bridge between the web and mobile phones. Along with many other applications, Twitter introduced their own terminology. A follower is someone who registered to be notified about updates of another user while being followed obviously means that someone else wants to stay in touch with you and is reading your updates.
