Second life...and some.

Second life is first and foremost an adult site. It is an online community, no an online world or country, where people work, play, and socialise all as an avatar of themselves. The avatars are hand picked and changed by their puppeteer, they have clothes and accessories and friends all within second life.
To me, second life is a collection of ugly dark 'islands' created by people who don't care weather or not their particular plot of land is aesthetically pleasing.

Any positives of Second Life are that it could engage children who otherwise would not be interested in school, and it could expose children to a variety of people, places and cultures that they would not otherwise see from the classroom. Even if the teacher opened Second Life and was the only one to touch it (to monitor child use)it is still an extremely demanding technology as it would require an up to date graphics card and a reasonably quick internet system, neither of which my practicum school had. Also the school has some blocked sites and Second Life would surely be one of them.

Second Life in education is a site that shows you the pros of using second life in an educational manner and even suggests some places that a classroom or teacher could visit. Through this site we were shown a cool Macbeth Island where one goes in avatar form and is dropped into, and fully immersed in, the happenings of the play Macbeth. This is just one of many, according to Kim Flintoff, places within Second Life where children can go and have a positive learning experience.

Over all I do not think I will use Second Life either personally or professionally as it is impractical and a bit sketchy to take children to, and it does not interest or inspire me.
