So it's not surprising that coleges are rushing into SL.
Among them are a few expected names --Columbia, Harvard, Leeds Colege, and Stanford. University of Texas has four islands! The San Francisco museum of science, art and human perception has its Exploratium in SL. One university has held a 300 level writing seminar (on technology and society). Harvard had an 'immersive' seminar last year. The list goes on...
In one sense, Second Life is social media at its best --immersive, interactive, dynamic, and a totally opt-in environment. But it's the ability to engage in content that truly attracts me. Reuters has video, a news ticker, and downloadable documents in a rich multimedia experience you just could not have, even via a web 2.0 web site.
From the perspective of lectures, and student interacton, this will
be where many other social media tools --video and movies, IM,
pictures, flash animation, blogs and wikis come together.
