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 ? 

Not yet sure if it is a good news or not, but Air France has become the first airline in the world to offer an in-flight mobile phone service on international flights.

One Airbus A318 aircraft operating European routes has been fitted with a mini GSM base station to provides 123 passengers the possibility to :

• Send and receive sms and mms messages
• Send and receive emails via all phones with Internet access

During the second half of the trial, passengers will be able to make and receive phone calls, with the service being regulated to maintain passengers’ comfort and well-being.

If passengers kindly turn off ringing traffic data from/to an aircraft should not be a big deal, if not journeys may become quite annoying with uninterrupted flow of incoming messages ringing alert.

Hard to imagine how will be a long haul flight with full mobile phone services (voice and data) "offered" to passengers. 

At the end of the six-month trial, Air France will examine the feedback and comments made by customers to determine whether to launch this service on all its flights.

What is your feeling about the availability of in-flight mobile phone service ? 

For the technical part,
Air France uses Mobile OnAir onboard mobile telephony system, certified by EASA (European Aviation Safety Authority) which does not interfere with the radio-navigation instruments on this Airbus A318 and may only be used at cruising altitude once the new illuminated sign “Switch off your phone” is turned off (recycling the "no smoking" sign ?).  The system is activated at 3,000 metres (10,000 feet).

More about this trial on AirFrance site including a video of the 1st trial flight.
