I attended a conference in Second Life today. Or rather I eavesdropped on a conference since I generally find that on-line events tend to run in the background when you're at work. Whether you participate via an e-meeting tool or SL it's very easy to hide and do other things at the same time I'm afraid. So I half-listen to the speakers whilst writing e-mails, documents or answering phone calls. I imagine most people do the same unless something very special grabs your attention. However, it does allow you the luxury of being part of an event and hearing some of the content without the travelling and organisation (but minus the all-important networking and discussion).
One feature however did make me think. I sat at my desk looking into a screen where my SL avatar was sitting looking at another screen in SL that showed a film of other people at the real life conference looking at a screen showing someone's presentation. Then one of the presenters at the conference showed an e-meeting on the screen where a presenter somewhere else showed his presentation on a screen in the e-meeting tool.
It would have been fun if the guy in the e-meeting had shown a feed from SL showing us watching the conference watching him etc etc.
Magritte would have loved it.
