This NWN post, Rosedale leaving, does not surprise me. It seems a major management shift in parallel with a strategy shift was underway. I have been meaning to see more about the content policy, the class-action lawsuit against LL by content creators, and anything about new strategy.
All of these actions seem like mid-level, world-based responses/ How it will play out in terms of field dynamics and communities of users may be a great data slice for our papers.
I like Au’s two theories. I wonder if the physical interaction interface (the rig) is the more likely.
