One of the things I noticed is that when we were using text chat, it was our avatars talking, but as soon as we switched to voice chat, it was us. I wonder if that would happen if I were talking with someone I didn't know in real life, someone whose disembodied voice I wouldn't recognize. I certainly didn't recognize my friend in his avatar, at least not right away. I am also curious to meet people in real life whose avatars I've come to know.
Here are pictures of L1Aura talking with our colleague Tiak8 (who almost immediately mastered gestures like the shrug) and L1 with her husband Tich. You can see why she was confused and has since given Tich a makeover. The wonders of the virtual world. Tiak8's gesture below says it all.
