A voice you can trust

Linden Lab is reportedly close to including voice in the Second Life interface. Nate Combs makes some interesting comments about the use of voice in virtual worlds over at the Terra Nova blog. Most interesting from the perspective of the knowledge worker is the relationship he discusses between the use of voice and trust. Voice should increase trust, which makes the transfer of knowledge easier. But will the use of voice disturb other aspects of the virtual worlds experience? The issue merits some further investigation.
