Following last month's announcement that Linden Lab chief executive Philip Rosedale would be leaving his post to take over as chairman of the board, the Second Life developer has announced Mark Kingdon will take over as CEO starting May 15th.

Most recently, Kingdon served as CEO of online-oriented marketing firm Organic Inc., and has also worked for business incubator idealab! and professional services firm PricewaterhouseCoopers.

Said Kingdon in a press release, "To me, the CEO role at Linden Lab combines perfectly my passions for art and design, business and technology."

Making a curious comment on the technical history of online worlds, the executive added, "Until Second Life, we experienced the digital world passively in two dimensions. By enabling users to create a rich and immersive virtual world, Second Life is transforming the way we connect, collaborate, learn and transact online."
