Linden Lab have posted two useful stories on their blog that are worth passing on.
The second is a look at how an in-world meeting was held for 160 people in Second Life. The standout sentence for me was:
Gronstedt led all participants through a 30-minute training session and all speakers and exhibitors through a 60-minute training session to ensure that when the conference day arrived, everyone was ready to walk, talk, text chat, and participate in this new virtual event experience.
Half an hour to an hour of training to be able to participate isn’t that high a premium, although without doubt it’d be a disincentive to a lot of people. To me, that’s a big hurdle for one-off meetings but a more than worthwhile expense for a business using virtual meetings regularly. Of course, the enterprise solution that reduces the learning curve even further will have an advantage as enterprise comes on board with offerings that reduce real-world travel expenses.
