IBM Lotus Connections is IBM's social software suite for behind the firewall. I've been using and testing Connections at my previous job and I liked it a lot, especially the modules that let you work together on a task (Activities) and the del.icio.us like DogEar module. And now Forterra, the company behind There, released Olive 2.2; a 3D environment that tightly integrates with Lotus Connections,Sametime and other IBM software products. I haven't had the time to watch the demo yet, but here's the news as related by Luis Benitez: Lotus Connections goes 3D ! and by Ian Hughes on the IBM Eightbar blog: Some more good news Forterra Olive and Lotus Sametime.
In the same vein, and launched a few months ago: Rivers Run Red's Immersive Workspaces. While we're obviously way past the 3D hype of 2006 and 2007, there's apparently enough market for these products to be funded, developed and pushed. Does this mean we're finally getting near the plateau of productivity for 3D environments?
