Ten years ago-- three years into my first web 3D project-- the world wasn't ready for a 3D web. VRML couldn't get arrested, and if you dared utter "Immersive Web" you'd get a 3-head-count stare.
But now, it's all anyone can talk about. There are so many startups doing web-based virtual worlds these days that I've lost track. And Immersive Web has moved from a futurist notion to part of the "web 3.0" canon at light speed.
All of which is really gratifying. I don't mind that I was a few years ahead of my time. And I still can't say we've got it 100% figured out. I'm just glad it's finally happening... and that I'm a part of it. The company I co-founded, Vivaty, got major venture backing last summer. We recently came out of hiding and got some great press coverage in the New York Times and elsewhere.
