I came from an industry in 2000/2001 that put bells and whistles on websitess and clients lined up to spend money on a future no one could predict but were desperate to 'be there.'
How sober, academic institutions can throw money at some platforms like Second Life I can't fathom, to try these things yes, but not at the expense of other tools.
Better to be the 'late adopter' in this case, to pick up tools once others have shown they work. What's the inordinate hurry? The technology can only develop in one direction. It isn't going away.
Students, indeed any of us, will drop technology that doesn't work or meet expectations.
It has to be easy, obvious, accessible, cheap (ideally free), for whichever platform you wish to use it on: desktop, laptop ... even tablet and smart-phone.
I'm also reminded what I hear all about me .... 'acitivities, activities, activities.'
This does not need hi-tech (though it can). As I noticed in the General Forum someone is asking if text is more interactive than video.
