I found very interesting post on Tom Barrett's "ICT in my Classroom" blog about how Twitter is used as an educational tool.

Tom's post also describes where Twitter is positioned among other communications tools. Twitter is not a synchronous or an asynchronous communication system. It is rather both at once depending how channel's followers use it.

He makes a nice metaphoric comparison between Twitter and a flowing torrent where people can just stand by it and observes the flow. Some prefers to jump into while others simply do not pay much attention to the  stream.

Personally I am amazed to see how many different ways Twitter is used today. There are, indeed, lots of individuals (you and me) but also some politicians (Clinton, Obama, UK Prime Minister), Public Services (LA fire department, AmCross), Airlines, News agencies, etc.. which are increasingly using it, but not necessarily to interact with others but to broadcast content or information.

Is any company using Twitter for internal use only ? 

Emirates Airlines announced yesterday that passengers will no longer have to switch off their mobile phones and will be allowed to make calls and text people during their journey on-board.

The first flight with authorized mobile phone calls was made on 20th of March between Dubai and Casablanca on-board of an Emirates Airbus A340-300 fitted with AeroMobile system, which ensures mobile telephones operate at minimum power during flights and make sure mobile phone signal does not interfere with aircraft navigation equipments.

A second aircraft equipped with the same AeroMobile system will be in service shortly.

Rates were not published, but in 2007, cost per minute was estimated between 2.50 and 3.50 USD.
