During my interview with Linden Lab's new CEO Ebbe Altberg, the executive had this to say about Linden Lab's products beyond Second Life and Blocksworld: "“We’ll do some clean-up, there’s some things that are not as aligned." And indeed, only minutes after I was posting the interview (less than two weeks of Altberg being CEO), Linden Lab announced it was discontinuing dio, Versu, and Creatorverse -- all of which were 2D or text-based content creation platforms. This means Linden Lab's remaining products have a focus on 3D content creation and user interaction within a 3D space: Second Life and Creatorverse, of course, plus Patterns (Minecraft meets Doritos man) and Desura (digital distribution of user-made content, primarily 3D-based content, including game levels).
While dio, Versu, and Creatorverse have not gained much evident user traction, I believe that's also the case with Patterns. So this move doesn't seem to be strictly about killing unpopular products, but as Altberg suggested in my interview, focusing the company only on products more aligned around Second Life -- which I interpret to mean 3D interaction and building.
