Since there are a number of Arab users on Twitter but there are a lot more that do not use the micro-blogging network due to the barrier of language, Artwitter.com is using the Twitter application to deliver an interface in Arabic that supports right to left entry of tweets.
There aren’t many options available right now on Artwitter however, some features are missing, such as the ability to view other users’ timeline or search for posts. That’s mainly because the application is still in early beta state which means that it is being developed and tested and thus has lesser functionality.
According to Startup Arabia, the lacking features will be added later when the service becomes popular.
