Twitter

Twitter, founded by Jack Dorsey, Biz Stone, and Evan Williams in March 2006 (launched publicly in July 2006), is a social networking and micro-blogging service that allows users to post their latest updates. An update is limited by 140 characters and can be posted through three methods: web form, text message, or instant message. The company has been busy adding features to the product like Gmail import and search. They recently launched a new site section called “Explore” for external and third party tools that interact with Twitter and a new visualization tool called Twitter Blocks.

The service was started by Obvious Corp, who also started Odeo.

In April 2008 Twitter launched Twitter Japan in partnership with Digital Garage.

Twicco.jp is a group and community feature for Twitter (currently available only in Japan). In Loic Le Meur’s demo video you can see it lets users create and follow a group instead of an individual account. Twitter Japan, a joint venture with Digital Garage, was already differentiating itself from the US version with ads in the feeds and therefor a monetization option right from the beginning.

Twitter allows users to post text updates via SMS, instant messaging, email, Twitter’s website and third party applications. Users have their own profile page that displays their latest updates. In addition, users can become “friends” with one another, or simply be a “follower.” Other than reading another person’s profile page, a user can also receive others’ updates through text messages, RSS or third party applications.

Twitter itself is a free service, though users may have to pay text messaging charges to the phone carriers.
