Persona differentiation in Second Life

I've been in Sl for a couple of weeks, and, inspired by Gwyneth Llewelyn's post on the generations of SL users and Aimee Weber's post on SL political "parties", I've Identified another SL dichotomy.

On one hand are those who view their avatars as extensions of their RL personalities. They may have different names or look different, but these folks will discuss their First Lives in world. In that sense their avatar "is" them.

On the other side are those who keep their First Lives and Second Lives strictly separated. They refuse to discuss their first lives in world, and may not discuss their second lives outside of the metaverse. My first reaction is to view this as escapist, but i'm certainly in no psition to judge.

This raises several interesting questions:

Does one group spend more time in world than the other?

How do the two groups behave differently in terms of their reaction to server outages, TOS / code changes, etc.

What about people like Anshe Chung (No, I've never met her) whose avatar is better known in RL than the person behind it?

Just a few late night thoughts.
