I played with that platform a bit for its possible use in education. I was blown away by what it provided so many years back. SL I think is one of the best digital life environment still out there. What I would have hoped for is that there was a DL (Digital Life) along with SL (Second Life) where users would use their real names and real like avatars. Would have been lot more fun for teachers to be meeting their students and people meeting their friends in this environment knowing who they are. I think SL limited themselves by this little restriction.
