No confirmation on this from Linden Lab but apparently Rodvik Humble has left the Lab to start a new company.

I wouldn't call Humble a "star" as the article says. I think he did some good things but overall his approach did not match the culture of Second Life at all. It seems like he was more about random shots than any real strategy.
